refactor: 统一账单列表组件，封装 BillListComponent

- 创建 BillListComponent 组件（基于 v2 风格，紧凑布局） - 支持筛选（类型、分类、日期范围）和排序（金额、时间） - 支持分页加载、左滑删除、点击详情、多选模式 - 支持 API 自动加载和 Custom 自定义数据两种模式 - 迁移 6 个页面/组件到新组件： - TransactionsRecord.vue - EmailRecord.vue - ClassificationNLP.vue - UnconfirmedClassification.vue - BudgetCard.vue - ReasonGroupList.vue - 删除旧版 TransactionList 组件 - 保留 CalendarV2 的特殊版本（有专用功能） - 添加完整的使用文档和 JSDoc 注释

+# BillListComponent 使用文档
+
+## 概述
+
+`BillListComponent` 是一个高内聚的账单列表组件，基于 CalendarV2 风格设计，支持筛选、排序、分页、左滑删除、多选等功能。已替代项目中的旧版 `TransactionList` 组件。
+
+**文件位置**: `Web/src/components/Bill/BillListComponent.vue`
+
+---
+
+## Props
+
+### dataSource
+- **类型**: `String`
+- **默认值**: `'api'`
+- **可选值**: `'api'` | `'custom'`
+- **说明**: 数据源模式
+  - `'api'`: 组件内部调用 API 获取数据（支持分页、筛选）
+  - `'custom'`: 父组件传入数据（通过 `transactions` prop）
+
+### apiParams
+- **类型**: `Object`
+- **默认值**: `{}`
+- **说明**: API 模式下的筛选参数（仅 `dataSource='api'` 时有效）
+- **属性**:
+  - `dateRange`: `[string, string]` - 日期范围，如 `['2026-01-01', '2026-01-31']`
+  - `category`: `String` - 分类筛选
+  - `type`: `0 | 1 | 2` - 类型筛选（0=支出, 1=收入, 2=不计入）
+
+### transactions
+- **类型**: `Array`
+- **默认值**: `[]`
+- **说明**: 自定义数据源（仅 `dataSource='custom'` 时有效）
+
+### showDelete
+- **类型**: `Boolean`
+- **默认值**: `true`
+- **说明**: 是否显示左滑删除功能
+
+### showCheckbox
+- **类型**: `Boolean`
+- **默认值**: `false`
+- **说明**: 是否显示多选复选框
+
+### enableFilter
+- **类型**: `Boolean`
+- **默认值**: `true`
+- **说明**: 是否启用筛选栏（类型、分类、日期、排序）
+
+### enableSort
+- **类型**: `Boolean`
+- **默认值**: `true`
+- **说明**: 是否启用排序功能（与 `enableFilter` 配合使用）
+
+### compact
+- **类型**: `Boolean`
+- **默认值**: `true`
+- **说明**: 是否使用紧凑模式（卡片间距 6px）
+
+### selectedIds
+- **类型**: `Set`
+- **默认值**: `new Set()`
+- **说明**: 已选中的账单 ID 集合（多选模式下）
+
+---
+
+## Events
+
+### @load
+- **参数**: 无
+- **说明**: 触发分页加载（API 模式下自动处理，Custom 模式可用于通知父组件）
+
+### @click
+- **参数**: `transaction` (Object) - 被点击的账单对象
+- **说明**: 点击账单卡片时触发
+
+### @delete
+- **参数**: `id` (Number | String) - 被删除的账单 ID
+- **说明**: 删除账单成功后触发
+
+### @update:selectedIds
+- **参数**: `ids` (Set) - 新的选中 ID 集合
+- **说明**: 多选状态变更时触发
+
+---
+
+## 使用示例
+
+### 示例 1: API 模式（组件自动加载数据）
+
+```vue
+<template>
+  <BillListComponent
+    data-source="api"
+    :api-params="{ type: 0, dateRange: ['2026-01-01', '2026-01-31'] }"
+    :show-delete="true"
+    :enable-filter="true"
+    @click="handleBillClick"
+    @delete="handleBillDelete"
+  />
+</template>
+
+<script setup>
+import BillListComponent from '@/components/Bill/BillListComponent.vue'
+
+const handleBillClick = (transaction) => {
+  console.log('点击账单:', transaction)
+  // 打开详情弹窗等
+}
+
+const handleBillDelete = (id) => {
+  console.log('删除账单:', id)
+  // 刷新统计数据等
+}
+</script>
+```
+
+### 示例 2: Custom 模式（父组件管理数据）
+
+```vue
+<template>
+  <BillListComponent
+    data-source="custom"
+    :transactions="billList"
+    :loading="loading"
+    :finished="finished"
+    :show-delete="true"
+    :enable-filter="false"
+    @load="loadMore"
+    @click="viewDetail"
+    @delete="handleDelete"
+  />
+</template>
+
+<script setup>
+import { ref } from 'vue'
+import BillListComponent from '@/components/Bill/BillListComponent.vue'
+import { getTransactionList } from '@/api/transactionRecord'
+
+const billList = ref([])
+const loading = ref(false)
+const finished = ref(false)
+
+const loadMore = async () => {
+  loading.value = true
+  const response = await getTransactionList({ pageIndex: 1, pageSize: 20 })
+  if (response.success) {
+    billList.value = response.data
+    finished.value = true
+  }
+  loading.value = false
+}
+
+const viewDetail = (transaction) => {
+  // 查看详情
+}
+
+const handleDelete = (id) => {
+  billList.value = billList.value.filter(t => t.id !== id)
+}
+</script>
+```
+
+### 示例 3: 多选模式
+
+```vue
+<template>
+  <BillListComponent
+    data-source="custom"
+    :transactions="billList"
+    :show-checkbox="true"
+    :selected-ids="selectedIds"
+    :show-delete="false"
+    :enable-filter="false"
+    @update:selected-ids="selectedIds = $event"
+  />
+  
+  <div v-if="selectedIds.size > 0">
+    已选中 {{ selectedIds.size }} 条
+    <van-button @click="batchDelete">批量删除</van-button>
+  </div>
+</template>
+
+<script setup>
+import { ref } from 'vue'
+import BillListComponent from '@/components/Bill/BillListComponent.vue'
+
+const billList = ref([...])
+const selectedIds = ref(new Set())
+
+const batchDelete = () => {
+  // 批量删除逻辑
+}
+</script>
+```
+
+---
+
+## 注意事项
+
+1. **数据源模式选择**:
+   - 如果需要自动分页、筛选，使用 `dataSource="api"`
+   - 如果需要自定义数据管理（如搜索、离线数据），使用 `dataSource="custom"`
+
+2. **筛选功能**:
+   - `enableFilter` 控制筛选栏的显示/隐藏
+   - 筛选栏包括：类型、分类、日期范围、排序四个下拉菜单
+   - Custom 模式下，筛选仅在前端过滤，不会调用 API
+
+3. **删除功能**:
+   - 组件内部自动调用 `deleteTransaction` API
+   - 删除成功后会派发全局事件 `transaction-deleted`
+   - 父组件通过 `@delete` 事件可执行额外逻辑
+
+4. **多选功能**:
+   - 启用 `showCheckbox` 后，账单项左侧显示复选框
+   - 使用 `v-model:selectedIds` 或 `@update:selectedIds` 同步选中状态
+
+5. **样式适配**:
+   - 组件自动适配暗黑模式（使用 CSS 变量）
+   - `compact` 模式适合列表视图，舒适模式适合详情查看

+
+## 与旧版 TransactionList 的差异
+
+| 特性 | 旧版 TransactionList | 新版 BillListComponent |
+|------|---------------------|----------------------|
+| 数据管理 | 仅支持 Custom 模式 | 支持 API + Custom 模式 |
+| 筛选功能 | 无内置筛选 | 内置筛选栏（类型、分类、日期、排序） |
+| 样式 | 一行一卡片，间距大 | 紧凑列表，间距 6px |
+| 图标 | 无分类图标 | 显示分类图标和彩色背景 |
+| Props 命名 | `show-delete` | `show-delete`（保持兼容） |

+- 组件实现: `Web/src/components/Bill/BillListComponent.vue`
+- API 接口: `Web/src/api/transactionRecord.js`
+- 设计文档: `openspec/changes/refactor-bill-list-component/design.md`
+

+
+## 常见问题
+
+**Q: 如何禁用筛选栏？**  
+A: 设置 `:enable-filter="false"`
+
+**Q: Custom 模式下分页如何实现？**  
+A: 父组件监听 `@load` 事件，追加数据到 `transactions` 数组，并控制 `loading` 和 `finished` 状态
+
+**Q: 如何自定义卡片样式？**  
+A: 使用 `compact` prop 切换紧凑/舒适模式，或通过全局 CSS 变量覆盖样式
+
+**Q: CalendarV2 为什么还有单独的 TransactionList？**  
+A: CalendarV2 的 TransactionList 有特定于日历视图的功能（Smart 按钮、特殊 UI），暂时保留

 ## ANTI-PATTERNS (THIS LAYER)

 - Don't access APIs directly (use api/ modules)
 - Avoid inline styles (use SCSS modules)

 ## UNIQUE STYLES
