feat: implement custom fields, gantt view, calendar view, and file encryption

- Custom Fields (FEAT-001):
  - CustomField and TaskCustomValue models with formula support
  - CRUD API for custom field management
  - Formula engine for calculated fields
  - Frontend: CustomFieldEditor, CustomFieldInput, ProjectSettings page
  - Task list API now includes custom_values
  - KanbanBoard displays custom field values

- Gantt View (FEAT-003):
  - TaskDependency model with FS/SS/FF/SF dependency types
  - Dependency CRUD API with cycle detection
  - start_date field added to tasks
  - GanttChart component with Frappe Gantt integration
  - Dependency type selector in UI

- Calendar View (FEAT-004):
  - CalendarView component with FullCalendar integration
  - Date range filtering API for tasks
  - Drag-and-drop date updates
  - View mode switching in Tasks page

- File Encryption (FEAT-010):
  - AES-256-GCM encryption service
  - EncryptionKey model with key rotation support
  - Admin API for key management
  - Encrypted upload/download for confidential projects

- Migrations: 011 (custom fields), 012 (encryption keys), 013 (task dependencies)
- Updated issues.md with completion status

# Proposal: Add Custom Fields
**Change ID:** `add-custom-fields`
**Issue Reference:** `FEAT-001` (issues.md)
**Status:** Draft
**Author:** Claude
**Date:** 2026-01-05
## Summary
實作自定義欄位功能,允許專案管理者為任務新增自定義欄位,包含文字、數字、下拉選單、日期、人員標籤和公式等類型。
## Motivation
目前系統僅支援固定的任務欄位(標題、描述、狀態、優先級等)。不同專案可能需要追蹤特定資料,例如:
- 半導體製程:封裝類型、機台編號、預計良率
- 軟體開發Sprint 編號、Story Points、影響版本
- 行銷活動:活動代碼、預算類別、目標受眾
自定義欄位讓專案管理者可以根據需求彈性擴展任務資料結構。
## Scope
### In Scope
- Backend: CustomField 和 TaskCustomValue models
- Backend: Custom fields CRUD API endpoints
- Backend: Formula field 計算引擎
- Frontend: Custom fields 管理 UI專案設定頁面
- Frontend: Task form 動態渲染自定義欄位
- Frontend: Task list/kanban 顯示自定義欄位值
### Out of Scope
- 跨專案共用欄位定義
- 自定義欄位匯入/匯出
- 複雜公式函數(僅支援基本數學運算)
## Design Decisions
### 欄位類型
| Type | 說明 | 儲存格式 |
|------|------|----------|
| text | 單行文字 | VARCHAR |
| number | 數字 | DECIMAL |
| dropdown | 下拉選單 | VARCHAR (選項儲存於 options JSON) |
| date | 日期 | DATE |
| person | 人員標籤 | UUID (FK -> users) |
| formula | 公式計算 | DECIMAL (計算結果) |
### 公式欄位
- 支援基本數學運算:`+`, `-`, `*`, `/`
- 可引用其他數字欄位:`{field_name}`
- 可引用任務內建欄位:`{original_estimate}`, `{time_spent}`
- 範例公式:`{time_spent} / {original_estimate} * 100`
### API 設計
```
POST /api/projects/{project_id}/custom-fields # 新增欄位定義
GET /api/projects/{project_id}/custom-fields # 列出所有欄位
PUT /api/custom-fields/{field_id} # 更新欄位定義
DELETE /api/custom-fields/{field_id} # 刪除欄位(含所有值)
# 欄位值透過現有 task API 操作
PUT /api/tasks/{task_id} # body 包含 custom_values
```
## Affected Specs
| Spec | Change Type |
|------|-------------|
| task-management | MODIFIED (Custom Fields requirement 實作細節) |
## Risks & Mitigations
| Risk | Mitigation |
|------|------------|
| 公式欄位循環引用 | 建立欄位時驗證公式不引用自己或形成循環 |
| 大量自定義欄位影響效能 | 限制每專案最多 20 個自定義欄位 |
| 刪除欄位遺失資料 | 刪除前顯示確認對話框,說明將刪除所有相關值 |
## Dependencies
- 無外部依賴
- 需要現有 tasks API 支援
