fix(numpad): 全部按键 @click 换 @pointerdown.left，零延迟

第一阶段（touch-action: manipulation）只解了浏览器双击缩放延迟，但 F7
内部 tap 合成 + active-state 检测仍让 @click 比 pointerdown 慢一拍。
完全弃用 @click：

- 16 个按键（数字 0-9、运算 ×−+、C 清空、小数点/双零、OK 确认）改 @pointerdown.left
- 触屏 button=0 始终满足 .left 修饰符
- 桌面右键 button=2 不会误触发
- F7 active-state 视觉反馈基于独立 touchstart/touchend 监听，按下效果保留
- 退格键的 pointer 事件方案在上个 commit 已实现，本次不动

+
+---
+
+## 仓库拓扑
+
+```
+github.com/mayswind/ezbookkeeping       （上游）
+        │  Gitea pull mirror（后台异步）
+        ▼
+git.zhengchentao.win/mirror/ezbookkeeping   （只读镜像）
+        │  CI workflow 拉过来
+        ▼
+git.zhengchentao.win/dev/ezbookkeeping     （origin，本地唯一 remote）
+```
+
+本地 `git remote -v` 只有 origin 一项，**没有手工配 upstream**。上游同步通过 custom 分支上的 workflow 在服务端完成，不是本地操作。
+
+---
+
+## 两个分支的职责（必须先理解，否则会改错地方）
+
+| 分支 | 职责 | force push? |
+|---|---|---|
+| `main` | **锚定上游 release tag**（当前 v1.4.0）。被 `.gitea/workflows/sync-upstream.yml` `git reset --hard <tag>` 覆写。**别在 main 上做任何改动** | 是（由 CI 做） |
+| `custom` | **所有个人改动 + workflow 文件都在这**：信用额度功能、UI 调整、个人需求清单、`.gitea/workflows/*.yml` 等。具体改动清单见 [`FORK.md`](FORK.md)。日常开发分支，**default branch** | 是（rebase 后人工做） |
+
+⚠️ **default branch 是 `custom`**。`git clone` 默认 checkout custom，直接是开发分支。
+
+### 历史：曾经存在过的 ci 分支（已退役）
+
+2026-05-02 之前曾经有第三个分支 `ci`，最初设计是把 `.gitea/workflows/*.yml` 单独放它上面以"meta/code 分离"。两周后发现 Gitea Actions runs 列表显示的 commit 是 workflow 文件所在 commit（即 ci 的 HEAD），不是被构建的代码 commit，UX 误导性强。
+
+把 workflow 挪回 custom 之后：
+- runs 列表 commit = 真实代码 commit ✅
+- `git clone` 默认落 custom 直接是开发分支 ✅
+- rebase 上游时 workflow 跟 custom 一起平移 ✅
+- 代价：失去"workflow 与代码完全独立"的设计美感 —— 这个分离原本就是过度设计
+
+**ci 分支于 2026-05-02 删除**，仅保留这段说明给后续 Claude 会话理解 git log 里"workflow 文件迁到 custom"这条提交（commit `555ecc1a`）的来龙去脉。**workflow 改动直接在 custom 上做**。
+
+---
+
+## custom 分支 workflow 清单
+
+`.gitea/workflows/` 当前有 2 个 workflow（2026-05-04 起 build+deploy 合并为单 workflow 双 job）：
+
+| 文件 | 触发 | 干什么 | 状态 |
+|---|---|---|---|
+| `sync-upstream.yml` | 手动（`workflow_dispatch`，可填 tag） | 服务端把 `dev/main` 强制 reset 到 mirror 上的指定 release tag（默认最新），然后 `push --force-with-lease` + 推 tags | ✅ 在用 |
+| `build-image.yml` | **自动**（push 到 custom 触发，`paths-ignore` 屏蔽 `**.md` / `.gitignore` / `LICENSE` / `screenshot/**` / `sync-upstream.yml`）+ 手动备选 | **两个 job 串联在同一 run 里**：①`build` job 装 buildkit v0.13.2 → 登录 Gitea registry → 构建镜像（带 OCI 标签 source/revision，Gitea 自动关联包到 repo）→ push 到 `git.zhengchentao.win/dev/ezbookkeeping:<hash>` 与 `:latest`，`build-args: BUILD_PIPELINE=1` 跳过活 API 测试。②`deploy` job (`needs: build`) 登录 registry → clone nas-infra → `docker compose pull && up -d` 重启 ezbookkeeping。私有 nas-infra 需要 `secrets.NAS_INFRA_TOKEN`，公开仓库不需要。UI 上 Actions 列表显示一条 run，run 详情里 dependency graph 显示 build → deploy | ✅ 日常发布通道 + 自动 CD |
+
+**已删**：
+- `docker-snapshot.yml` / `docker-release.yml`（2026-05-02，依赖未配的 `secrets.DOCKER_REPO`，永远失败）
+- `deploy.yml`（2026-05-04，合并进 `build-image.yml` 作为第二个 job，理由：原先 `workflow_run` 链触发会在 Actions 列表产生两条独立 run，UX 割裂；合并后单 run + dependency graph 看 build/deploy 状态一目了然）
+
+需要时再从 git 历史 cherry-pick 回来。
+
+---
+
+## 同步发布流程（rebase 模型）
+
+1. 上游出新 release（如 v1.4.0）→ Gitea pull mirror 自动把 tag 同步到 mirror
+2. 人工触发 `Sync from upstream` workflow → 服务端把 dev/main reset 到该 tag
+3. 本地 `git fetch && git checkout custom && git rebase origin/main`
+4. 解冲突（如有）→ 验证 → `git push --force-with-lease origin custom`
+5. **build-image workflow 自动触发**（force-push 也算 push 事件），构建新镜像；不需要手动点
+
+日常 feature commit 流程（全自动 CD）：
+
+1. 在 custom 上改代码 → commit → push
+2. **自动触发 build job**（除非只改了 `**.md` / `.gitignore` / `LICENSE` / `screenshot/**` / `sync-upstream.yml`）
+3. build 成功 → **同 run 内 deploy job 接力跑**（`needs: build` 串联）：clone nas-infra → docker compose pull → up -d
+4. 整条 push → build → deploy 链路无人工介入，UI 上是单条 run
+
+**并发取消策略**：`build-image.yml` 设了 `concurrency.cancel-in-progress: true`，连续多次 push 时**只构建+部署最新那一次**（同 run 里 build/deploy 是原子单元，一起取消）。例：连续 3 次 push 间隔 30 秒，第 1 次 build 跑到 30%、第 2 次到来取消它、第 3 次又取消第 2，最终只 build + deploy 第 3 次的代码。省 CI 时间又保证最终一致性。
+
+如果想跳过 build/deploy（例如手动多次 push 调试），commit 时只改文档相关文件即可（落在 paths-ignore 范围内）。如果想强制重打某个旧 commit，去 Actions UI 手动触发 `Build Docker Image`，填要打包的 branch / tag —— 注意手动触发也会跑 deploy job，**没有"只重新部署不重新 build"的单点入口了**（合并的代价，原 `deploy.yml` 那条路径已废）。临时只想重启容器：直接到 NAS 上 `docker compose up -d` 或在 Actions UI 临时禁用 deploy job。
+
+**为什么 rebase 不 merge**：个人项目，无团队协作语义要保留，线性历史更清爽。
+
+---
+
+## 给后续 Claude 会话的明确提示
+
+- 用户说"我的分支" / "切换到我的分支" → 指 `custom`
+- 用户说"rebase main" → 指 `git rebase origin/main`，目标是把 custom 的改动叠到最新上游 tag 之上
+- **不要在 `main` 分支上提交任何东西**（会被 CI 覆写）
+- **workflow 文件改动直接在 custom 上做**（2026-05-02 起，不再是 ci 分支）
+- force-push custom 是常规操作，但每次用 `--force-with-lease`，不直接 `--force`
+- 如果发现本地配了 upstream remote，那是历史遗留，不要依赖；以 origin/main 为准
+- `.claude/` 在 `.gitignore` 里（个人本地配置不入库），但 `CLAUDE.md` 本身入库
+
+---
+
+## 同步历史
+
+- **2026-05-01**：rebase custom → origin/main (v1.4.0)。22 个 custom-only 提交（含一个旧的 `Merge branch 'main' into myrequirement` commit）压平为 21 个线性提交。已 force-push origin/custom（`08c69042` → `fe265259`）。
+- **2026-05-02**：修 Gitea Actions `Build Docker Image` 工作流。三层故障，全部不在本仓库代码里：
+  - **TLS 雷**：`docker login` 走 host 进程不命中 PREROUTING REDIRECT，且 v6 撞 DSM nginx 的 CF Origin Cert。NAS 侧修：iptables 补 OUTPUT 对称规则 + `/etc/hosts` 显式 v4 兜底。详见 obsidian vault [[NAS/notes/内网证书路径]] §三.5/§三.6
+  - **buildkit 内核兼容**：runc 1.2+ 撞 DSM 4.4 内核。`.gitea/workflows/build-image.yml` 钉 `moby/buildkit:v0.13.2`（commit `acdbb5bf`）
+  - **backend 单元测试撞活 API**：`pkg/exchangerates/` 的 `TestExchangeRatesApiLatestExchangeRateHandler_*` 跑活 API（加拿大银行 / 乌兹别克央行），国内访问超时。upstream Dockerfile 已设 `ARG BUILD_PIPELINE`，测试代码看到 `BUILD_PIPELINE=1 && CHECK_3RD_API!=1` 时早退。修：workflow 加 `build-args: BUILD_PIPELINE=1`（commit `2dd8f099`），对齐上游 GH Actions
+- **2026-05-02 (后续)**：workflow 文件从 ci 分支迁到 custom，default branch 切到 custom（commit `555ecc1a`），随后**删掉 ci 分支**。原因：Gitea Actions runs 列表的 commit 字段一直显示 ci 的 workflow commit，不是被构建的代码 commit，UX 误导性强。挪到 custom 后列表直接显示真实代码 commit。同时清理上游残留的 `docker-release.yml` / `docker-snapshot.yml`（依赖未配的 `secrets.DOCKER_REPO`，永远失败）。仓库回到朴素的 main + custom 双分支模型
+- **2026-05-02 (numpad fix)**：FORK.md #11 定位 + 修复。小键盘点击卡顿真因是 `.numpad-button` 的 `touch-action: none`（上游 e178a079 引入）与 F7 tap 处理叠加，改为 `touch-action: manipulation`（commit `75b4d78d`）
+- **2026-05-04**：把 `deploy.yml` 合并进 `build-image.yml` 作为第二个 job（`needs: build`），删除 `deploy.yml`。原先 `workflow_run` 链路会在 Actions 列表产生两条独立 run（build 完一条、deploy 又一条），用户视角割裂；合并后 UI 列表单条 run，run 详情里 dependency graph 显示 build → deploy 串联。代价：失去"不 rebuild 只 redeploy"的 UI 单点触发，临时只想重启容器需直接 ssh NAS 跑 compose。`paths-ignore` 移除已不存在的 `deploy.yml` 项
+
+## 给后续 Claude 会话：CI 故障排查路径
+
+如果 Gitea Actions build 又炸，按 NAS 域问题 vs 仓库代码问题分别排查：
+
+| 现象 | 大概率位置 | 文档 |
+|---|---|---|
+| `Login to Gitea Container Registry` 步骤报 `x509: certificate signed by unknown authority` | NAS 网络层（iptables / dnsmasq / DSM nginx 占 443） | obsidian vault `NAS/notes/内网证书路径.md` + `NAS/notes/IPv6 设计.md` |
+| `Build and push` 步骤里 `RUN ...` 在第二条之内就炸 `unsafe procfs detected` 之类 | buildkit/runc 与 DSM 内核版本 | `.gitea/workflows/build-image.yml` 的 `driver-opts` |
+| `Failed to pass unit testing` / `Failed to pass lint checking`（build.sh 报） | **先看 Dockerfile 顶部 `ARG`**，多半是 CI 跳过开关没传（如 `BUILD_PIPELINE` / `CHECK_3RD_API` / `SKIP_TESTS`）。**不要先去改测试代码** | `Dockerfile` 顶部 ARG + `.gitea/workflows/build-image.yml` 的 `build-args` |
+| `actions/checkout` 报 fetch 失败 | Gitea SSH/HTTPS 路径或 token 权限 | gitea-runner 的 `GITEA_RUNNER_REGISTRATION_TOKEN` + NPM `git.zhengchentao.win` 的 Advanced 配置 |
+| Dockerfile 里某条指令业务逻辑报错 | 真正的代码问题 | 本仓库 `Dockerfile` |
+
+**通用排查原则**：build.sh 报的"测试失败 / lint 失败"先看是不是上游已经设计了 CI 跳过路径。Dockerfile 的 `ARG` + `build.sh` 内的 `os.Getenv()` 检查通常成对出现（如 `BUILD_PIPELINE=1` → 跳过 3rd API 测试，`SKIP_TESTS=...` → 跳过指定测试名）。对齐上游 `.github/actions/` 下的传参，绝大多数情况能直接对齐。

+
+---
+
+## 一、账户功能
+
+### 1. 🟢 信用卡账户：额度与可用额度
+**描述：** 为信用卡类型账户新增「信用额度」字段，在账户列表显示可用额度。
+
+**已完成：**
+- 后端：`AccountExtend` JSON blob 新增 `CreditLimit` 字段（无需数据库迁移）
+- API：`AccountCreateRequest` / `AccountModifyRequest` / `AccountInfoResponse` 增加 `creditLimit`
+- 前端 model：`Account` 类增加 `creditLimit` 字段，同步序列化/反序列化
+- 移动端 EditPage：CreditCard 分类时显示信用额度输入项（数字键盘）
+- 桌面端 EditDialog：CreditCard 分类时显示信用额度输入框（`amount-input`）
+- 移动端 ListPage：账户名下方显示「可用额度: ¥xxx」（= `creditLimit + balance`）
+- 桌面端 ListPage：账户卡片余额旁显示「Available: ¥xxx」
+- 语言包：中英繁均已添加 `"Credit Limit"` / `"Available"`
+
+### 2. 🟢 按账户筛选交易时顶部显示账户信息卡
+**描述：** 在按单个账户筛选的交易列表顶部，显示账户图标、名称和余额/可用额度。
+
+**已完成：**
+- 仅单账户筛选时（`queryAllFilterAccountIdsCount === 1`）显示，多账户/全量时隐藏
+- 信用卡账户显示「欠款 · 可用 ¥xxx」，普通账户显示余额
+- 移动端：toolbar 下方插入账户信息卡片；桌面端：日期范围行下方插入 tonal 样式账户卡片
+- 多子账户（`MultiSubAccounts`）一级账户：使用 `getAccountSubAccountBalance` 获取汇总余额及正确币种，修复 `currency = '---'` 导致货币符号不显示的问题
+- 涉及文件：`src/views/mobile/transactions/ListPage.vue`、`src/views/desktop/transactions/ListPage.vue`
+
+### 3. 🟢 账户编辑页直接修改余额（自动插入调整记录）
+**描述：** 在账户编辑页修改余额字段，保存时自动计算差值并插入一条「余额调整」类型交易。
+
+**已完成：**
+- 后端：移除「账户已有交易时不允许添加 ModifyBalance」的限制
+- 后端：`Amount` 与 `RelatedAccountAmount` 均存储 delta；创建时 `balance += delta`，删除时 `balance -= delta`，修改时 `balance = balance - oldDelta + newDelta`
+- 后端响应：`ToTransactionInfoResponse` 对 ModifyBalance 类型返回 `RelatedAccountAmount` 作为 `sourceAmount`
+- 前端 store：新增 `adjustAccountBalance({ accountId, targetBalance, currentBalance })` 函数，发送 `sourceAmount = delta`
+- 移动端 EditPage：余额字段对已有账户解除只读；保存时若余额变化先调 `adjustAccountBalance`；捕获 `NothingWillBeUpdated (200004)` 视为成功
+- 桌面端 EditDialog：同上逻辑，支持多子账户逐一调整
+- 「调整余额」入口仅在账户编辑页，已从账户列表「更多」菜单移除
+- 涉及文件：`pkg/services/transactions.go`、`pkg/models/transaction.go`、`src/stores/transaction.ts`、`src/views/mobile/accounts/EditPage.vue`、`src/views/desktop/accounts/list/dialogs/EditDialog.vue`
+
+---
+
+## 二、记账页面
+
+### 4. 🟢 记账页选择账户后显示余额/可用额度
+**描述：** 在记账页面选择账户后，在账户行显示该账户的当前余额或信用卡可用额度。
+
+**已完成：**
+- 信用卡账户（有 `creditLimit`）：显示「欠款金额 · 可用 ¥xxx」
+- 普通负债账户：显示欠款正数；普通资产账户：显示余额
+- 转账类型时源账户和目标账户均显示
+- 移动端：账户列表项 `footer` 字段；桌面端：`two-column-select` 的 `custom-selection-secondary-text`
+- 涉及文件：`src/views/mobile/transactions/EditPage.vue`、`src/views/desktop/transactions/list/dialogs/EditDialog.vue`
+
+### 5. ❓ 记录上次选择的账户（待定）
+**描述：** 新建交易时，默认选中上次使用的账户。
+
+**实现思路：**
+- 保存账户 ID 到 `localStorage`，打开记账页时读取并预选
+- 涉及文件：`src/views/mobile/transactions/EditPage.vue`、`src/lib/settings.ts`
+
+---
+
+## 三、小键盘
+
+### 6. 🟢 小键盘布局调整
+**描述：** 调整数字键盘布局。
+
+**已完成：**
+```
+[数值显示区              ] [ ⌫ ]
+  7     8     9      ×
+  4     5     6      −
+  1     2     3      +
+  C     0     .     OK
+```
+- ⌫ 单击退格；按住不放先删一位、约 500ms 后清空全部（长按响应细节见 #11 第二阶段）
+- C 一键清除全部
+- 涉及文件：`src/components/mobile/NumberPadSheet.vue`
+
+---
+
+## 四、交易详情
+
+### 7. 🟢 交易详情页增加「编辑」和「删除」入口（仅移动端）
+**描述：** 移动端交易详情页三点菜单中增加编辑和删除操作。PC 端详情直接在编辑弹窗中展示，无需额外入口。
+
+**已完成：**
+- 三点菜单：第一项「Edit」跳转编辑页，最后一项红色「Delete」确认后删除并返回
+- 从详情返回编辑页后自动刷新数据
+- 涉及文件：`src/views/mobile/transactions/EditPage.vue`
+
+---
+
+## 五、交易时间选择
+
+### 8. ❌ 点击交易时间标题默认打开日期选择（已回滚）
+**描述：** 原想让点击「Transaction Time」标题行时默认弹日期选择器。
+
+**为何回滚：** 改动改的是 `template #header` 那行 label 的点击 handler（`'time'` → `'date'`），实际操作中用户点的是 `template #title` 里的日期/时间文本。上游早在 commit `368322f9` 已实现"点哪走哪"的智能路由——点日期开日期选择器、点时间开时间选择器。所以这条改动**用户视角无可见差异**，纯空改，回滚到上游行为。
+
+**留档教训：** 改 UI 行为前先把"用户实际点哪个元素"摸清楚，别只看着 DOM 结构想当然。`#header` slot 只是上方的 label 行，正常用户极少触发。
+
+---
+
+## 六、分类选择
+
+### 9. 🟢 分类选择默认全部展开（仅移动端）
+**描述：** 在移动端记账页选择分类时，默认展开所有一级分类。PC 端使用不同的分类选择组件，无需此设置。
+
+**已完成：**
+- 设置存 localStorage（字段 `expandCategoryTreeByDefault`，默认 `false`），即时生效无需 reload；已加入云同步白名单（`ALL_ALLOWED_CLOUD_SYNC_APP_SETTING_KEY_TYPES`），可跨设备同步
+- `TreeViewSelectionSheet` 新增可选 prop `defaultExpanded`，`:opened` 改为 `props.defaultExpanded || isPrimaryItemHasSecondaryValue(item)`
+- 移动端 EditPage 三个分类 sheet（支出/收入/转账）均传入 `:default-expanded`
+- 设置仅在移动端设置页显示，PC 端无对应入口
+- 涉及文件：`src/components/mobile/TreeViewSelectionSheet.vue`、`src/views/mobile/transactions/EditPage.vue`、`src/views/mobile/SettingsPage.vue`
+
+---
+
+## 七、性能与动画
+
+### 10. 🟢 全局动画加速（仅移动端）
+**描述：** 移动端全局页面跳转及各类弹层动画加速。
+
+**已完成：**
+- 页面跳转、Sheet、ActionSheet、Popup、Dialog、Popover 动画时长从 300ms → 150ms
+- Tab 切换动画保持原样（设置中已有开关可控制）
+- 涉及文件：`src/styles/mobile/global.scss`
+
+### 11. 🟢 小键盘点击卡顿（三次修正）
+**描述：** 移动端小键盘点击有延迟感。
+
+**第一阶段（2026-05-02）`touch-action: none` 引发的 300ms 双击延迟：** 上游在 `.numpad-button` 上设了 `touch-action: none`（commit `e178a079` "code refactor" by MaysWind），与浏览器双击缩放检测叠加后保留了老式 300ms 点击延迟。
+- 修复：`.numpad-button` 的 `touch-action: none` 改为 `touch-action: manipulation`（W3C 标准"快速点击"值，禁双击缩放）
+
+**第二阶段（2026-05-08）退格键 `@taphold` 等待 750ms：** backspace 单点仍可感知延迟。根因是 `@click` + `@taphold` 让 F7 必须等 ~750ms 判别 tap vs hold，期间 click 被抑制。
+- 修复：弃用 `@click="backspace" @taphold="clear()"`，改为原生 `pointerdown`/`pointerup`/`pointercancel`/`pointerleave` + 自管定时器
+- 行为：单击立即删一位；按住不放先删一位、约 500ms 后清空全部
+
+**第三阶段（2026-05-08）所有数字/运算键也延迟：** 第一阶段修完后用户反馈数字键仍有"等一拍"感。怀疑 F7 整套 tap 处理（含 active-state 检测、`fastClicks` 兼容代码、tap-hold 全局监听）即便不显式声明 `@taphold` 也会给 `@click` 加上判别期。
+- 修复：把所有按键（数字 0-9、运算 ×−+、C 清空、小数点/双零、OK 确认）的 `@click` 全部换成 `@pointerdown.left`
+- 原理：`pointerdown` 在按下瞬间触发，绕开 F7 的 tap 合成路径。`.left` 修饰符限制只响应主键（触屏 button=0 始终满足，桌面右键不会误触发）
+- F7 的 `.active-state` 视觉反馈基于独立的 touchstart/touchend 监听，不依赖 `@click`，按下视觉效果保留
+
+涉及文件：`src/components/mobile/NumberPadSheet.vue`
+
+**附带认知：** 原 #11 假设是"全局点击响应慢"或"接口慢"，与 #12 离线缓存挂钩调研。实际诊断后跟那两条都无关——纯 F7 框架 tap 合成 + 双击缩放 + taphold 检测三者叠加。最终通过完全弃用 `@click` 改 pointer 事件解决。该认知值得记录避免后续误诊路径。
+
+---
+
+## 八、离线 / 缓存
+
+### 12. ❌ 本地优先 / 离线数据缓存（暂缓）
+**描述：** 交易数据本地缓存，优先展示缓存数据，后台静默拉取更新。
+
+**现状：** Service Worker 已实现静态资源缓存，但交易业务数据目前不做本地缓存。
+
+**为何难：**
+- 需引入 IndexedDB 存储交易/账户/分类数据
+- 需处理本地与服务端的数据同步、冲突解决
+- 属于架构级改动，工作量较大
+
+---
