fix: 修复账单删除功能并支持分析页面删除操作

- 将删除接口从 DELETE /api/bills/:id 改为 POST /api/bills/:id/delete 以兼容 SvelteKit 代理
- 分析页面组件 (TopExpenses/BillRecordsTable/DailyTrendChart) 支持删除并同步更新统计数据
- Review 接口改为直接查询 MongoDB 而非读取文件
- 软删除时记录 updated_at 时间戳
- 添加 .dockerignore 文件优化构建
- 完善 AGENTS.md 文档

 ## Code Style
 
-### TypeScript/Svelte
+### General
-**Prettier config:** Tabs, single quotes, no trailing commas, width 100
+- **Comments:** Existing comments often use Chinese for business logic explanations. Maintain this style where appropriate, but English is also acceptable for technical explanations.
+- **Conventions:** Follow existing patterns strictly. Do not introduce new frameworks or libraries without checking `package.json`/`go.mod`/`requirements.txt`.
 
-**Imports:**
+### TypeScript/Svelte (web/)
-```typescript
+- **Formatting:** Prettier (Tabs, single quotes, no trailing commas, printWidth 100).
-import { browser } from '$app/environment';  // SvelteKit
+- **Naming:** `PascalCase` for types/components/interfaces, `camelCase` for variables/functions.
-import { auth } from '$lib/stores/auth';     // Internal
+- **Imports:** Use `$lib` alias for internal imports.
-import type { UIBill } from '$lib/models/bill';
+  ```typescript
-```
+  import { browser } from '$app/environment';
+  import { auth } from '$lib/stores/auth';
+  import type { UIBill } from '$lib/models/bill';
+  ```
+- **Types:** Define interfaces for data models. Use `export interface`.
+- **Error Handling:** Check `response.ok`. Throw `Error` with status for UI to catch.
 
-**Types:**
+### Go Backend (server/)
-```typescript
+- **Structure:** `handler` (HTTP) → `service` (Logic) → `repository` (DB) → `model` (Structs).
-export interface UploadResponse {
+- **Tags:** Use `json` (snake_case) and `form` tags. Use `omitempty` for optional fields.
-  result: boolean;
+  ```go
-  message: string;
+  type UpdateBillRequest struct {
-  data?: UploadData;
+      Category *string `json:"category,omitempty" form:"category"`
-}
+  }
-```
+  ```
+- **Error Handling:** Return `500` for DB errors, `400` for bad requests. Wrap errors with context.
+  ```go
+  if err != nil {
+      c.JSON(http.StatusInternalServerError, Response{Result: false, Message: err.Error()})
+      return
+  }
+  ```
 
-**Naming:** PascalCase (types, components), camelCase (functions, variables)
+### Python Analyzer (analyzer/)
-
+- **Style:** PEP 8. Use `snake_case` for variables/functions.
-**Error handling:**
+- **Type Hints:** Mandatory for function arguments and return types.
-```typescript
+- **Models:** Use `pydantic.BaseModel` for API schemas.
-if (!response.ok) {
+  ```python
-  throw new Error(`HTTP ${response.status}`);
+  class CleanRequest(BaseModel):
-}
+      input_path: str
-// Handle 401 -> logout redirect
+      bill_type: Optional[str] = "auto"
-```
+  ```
-
+- **Docstrings:** Use triple quotes. Chinese descriptions are common for API docs.
-### Go Backend
-**Structure:** `handler/` → `service/` → `repository/` → MongoDB
-
-**JSON tags:** snake_case, omitempty for optional fields
-```go
-type UpdateBillRequest struct {
-    Category *string `json:"category,omitempty"`
-    Amount   *float64 `json:"amount,omitempty"`
-}
-```
-
-**Response format:**
-```go
-type Response struct {
-    Result  bool        `json:"result"`
-    Message string      `json:"message,omitempty"`
-    Data    interface{} `json:"data,omitempty"`
-}
-```
-
-**Error handling:**
-```go
-if err == repository.ErrNotFound {
-    c.JSON(http.StatusNotFound, Response{Result: false, Message: "not found"})
-    return
-}
-```
-
-### Python Analyzer
-**Style:** PEP 8, type hints, Pydantic models
-
-```python
-def do_clean(
-    input_path: str,
-    output_path: str,
-    bill_type: str = "auto"
-) -> tuple[bool, str, str]:
-```
-
-**Error handling:**
-```python
-if not success:
-    raise HTTPException(status_code=400, detail=message)
-```
 
 ## Key Patterns
 
-**API Flow:** Frontend (SvelteKit proxy) → Go API → MongoDB + Python analyzer
+- **API Flow:**
+  - Frontend talks to `server` (Go) via `/api` proxy.
+  - `server` handles auth, DB operations, and delegates complex file processing to `analyzer` (Python).
+  - `analyzer` cleanses CSV/Excel files and returns structured JSON/CSV to `server`.
 
-**Auth:** JWT tokens, Bearer header, 401 → logout redirect
+- **Authentication:**
+  - JWT based. Token stored in frontend.
+  - Header: `Authorization: Bearer <token>`.
+  - Backend middleware checks token. 401 triggers logout/redirect.
 
-**File Processing:** ZIP → extract → convert (GBK→UTF-8, xlsx→csv) → clean → import
+- **File Processing:**
-
+  - Flow: Upload (ZIP/XLSX) -> Extract/Convert (to UTF-8 CSV) -> Clean (normalize columns) -> Import to DB.
-**Testing:** Vitest + Playwright for frontend, Go test for backend
+  - `analyzer` uses `openpyxl` for Excel and regex for cleaning text.

+- `web/src/lib/api.ts` - Centralized API client methods.
-- `web/src/lib/models/` - UI data models
+- `web/src/lib/models/*.ts` - Frontend data models (should match backend JSON).
-- `server/handler/` - HTTP handlers
+- `server/handler/*.go` - HTTP endpoint definitions.
-- `server/service/` - Business logic
+- `server/repository/mongo.go` - MongoDB connection and queries.
-- `server/model/` - Go data structures
+- `analyzer/server.py` - FastAPI entry point and routing.
-- `analyzer/cleaners/` - Bill processing
+- `analyzer/cleaners/*.py` - Specific logic for Alipay/Wechat/JD bills.
-- `mock_data/*.zip` - Test data (password: 123456)
