feat: 实现 RBAC 权限系统和数据权限控制 (004-rbac-data-permission)

主要功能:
- 实现完整的 RBAC 权限系统(账号、角色、权限的多对多关联)
- 基于 owner_id + shop_id 的自动数据权限过滤
- 使用 PostgreSQL WITH RECURSIVE 查询下级账号
- Redis 缓存优化下级账号查询性能(30分钟过期)
- 支持多租户数据隔离和层级权限管理

技术实现:
- 新增 Account、Role、Permission 模型及关联关系表
- 实现 GORM Scopes 自动应用数据权限过滤
- 添加数据库迁移脚本(000002_rbac_data_permission、000003_add_owner_id_shop_id)
- 完善错误码定义(1010-1027 为 RBAC 相关错误)
- 重构 main.go 采用函数拆分提高可读性

测试覆盖:
- 添加 Account、Role、Permission 的集成测试
- 添加数据权限过滤的单元测试和集成测试
- 添加下级账号查询和缓存的单元测试
- 添加 API 回归测试确保向后兼容

文档更新:
- 更新 README.md 添加 RBAC 功能说明

# Tasks: RBAC 表结构与 GORM 数据权限过滤
**Input**: Design documents from `/specs/004-rbac-data-permission/`
**Prerequisites**: plan.md (required), spec.md (required for user stories), research.md, data-model.md, contracts/
**Tests**: REQUIRED per Constitution - Testing Standards (spec.md includes testing requirements)
**Organization**: Tasks are grouped by user story to enable independent implementation and testing of each story.
## Format: `[ID] [P?] [Story] Description`
- **[P]**: Can run in parallel (different files, no dependencies)
- **[Story]**: Which user story this task belongs to (e.g., US1, US2, US3)
- Include exact file paths in descriptions
## Path Conventions
- **Single project**: `internal/`, `pkg/`, `cmd/`, `migrations/`, `tests/` at repository root
- Paths follow the project structure defined in plan.md

## Dependencies & Execution Order
### Phase Dependencies
- **Setup (Phase 1)**: No dependencies - can start immediately
- **Foundational (Phase 2)**: Depends on Setup completion - BLOCKS all user stories
- **User Stories (Phase 3+)**: All depend on Foundational phase completion
- User Story 1 (US1) and User Story 2 (US2) are both P1 priority
- US2 depends on US1 completion (needs account models and stores)
- User Story 3 (US3) can start after US1 but benefits from US2 completion
- **Polish (Phase 6)**: Depends on all desired user stories being complete
### User Story Dependencies
- **User Story 1 (P1)**: Can start after Foundational (Phase 2) - No dependencies on other stories
- **User Story 2 (P1)**: Depends on US1 completion (uses AccountStore for GetSubordinateIDs)
- **User Story 3 (P2)**: Can start after US1, should integrate US2 components
### Within Each User Story
- Migrations before models
- Models before stores
- Stores before services
- Services before handlers
- Handlers before routes
- Tests can run in parallel with implementation but verify after
### Parallel Opportunities
**Phase 1 (Setup)**:
- T002, T003, T004 can run in parallel
**Phase 2 (Foundational)**:
- T006-T009 (context helpers) can run in parallel
- T011, T012 (routes) can run in parallel
**Phase 3 (US1)**:
- T024-T026 (rollback migrations) can run in parallel
- T027-T037 (GORM models) can run in parallel
- T042-T046 (stores except AccountStore) can run in parallel
- T51, T052 (services except Account) can run in parallel
- T054, T055 (handlers except Account) can run in parallel
- T060, T061 (role association methods) can run in parallel
- T063, T064 (routes except account) can run in parallel
- T065-T072 (tests) can run in parallel
**Phase 4 (US2)**:
- T075, T077 (model updates) can run in parallel
- T089, T090 (apply scope) can run in parallel
- T096-T101 (tests) can run in parallel
**Phase 5 (US3)**:
- T114, T115 (route files) can run in parallel
- T117, T118 (tests) can run in parallel
**Phase 6 (Polish)**:
- T119-T121 (documentation) can run in parallel
- Most quality gates can run in parallel
---
## Parallel Example: Phase 3 Models
```bash
# Launch all GORM models together:
Task T027: "Create Account model with GORM tags in internal/model/account.go"
Task T028: "Create Account DTO structures in internal/model/account_dto.go"
Task T029: "Create Role model with GORM tags in internal/model/role.go"
Task T030: "Create Role DTO structures in internal/model/role_dto.go"
Task T031: "Create Permission model with GORM tags in internal/model/permission.go"
Task T032: "Create Permission DTO structures in internal/model/permission_dto.go"
Task T033: "Create AccountRole model in internal/model/account_role.go"
Task T035: "Create RolePermission model in internal/model/role_permission.go"
Task T037: "Create DataTransferLog model in internal/model/data_transfer_log.go"
```

## Implementation Strategy
### MVP First (User Stories 1 + 2)
1. Complete Phase 1: Setup
2. Complete Phase 2: Foundational (CRITICAL - blocks all stories)
3. Complete Phase 3: User Story 1 (RBAC tables and CRUD)
4. Complete Phase 4: User Story 2 (Data permission filtering)
5. **STOP and VALIDATE**: Test both stories independently
6. Deploy/demo if ready - Core RBAC system functional
### Incremental Delivery
1. Complete Setup + Foundational → Foundation ready
2. Add User Story 1 → Test independently → RBAC tables and CRUD working
3. Add User Story 2 → Test independently → Data filtering working (MVP!)
4. Add User Story 3 → Test independently → Code refactored
5. Each story adds value without breaking previous stories
### Parallel Team Strategy
With multiple developers:
1. Team completes Setup + Foundational together
2. Once Foundational is done:
- Developer A: User Story 1 (models and CRUD)
- Developer B: Prepare User Story 2 tests (can start writing tests)
3. Once US1 is done:
- Developer A: User Story 2 (data permission filtering)
- Developer B: User Story 3 (refactoring)
4. Stories complete and integrate independently

## Summary
**Total Task Count**: 150 tasks (已移除 user/order 示例相关任务)
**Task Count per User Story**:
- Setup (Phase 1): 4 tasks
- Foundational (Phase 2): 8 tasks
- User Story 1 (Phase 3): 60 tasks
- User Story 2 (Phase 4): 26 tasks (移除了 T076, T077, T089, T090 合并)
- User Story 3 (Phase 5): 15 tasks (T114, T115 合并为 T114)
- Polish (Phase 6): 37 tasks
**Parallel Opportunities**: ~45 tasks marked [P]
**Independent Test Criteria per Story**:
- US1: Run migrations, verify tables, create test data, soft delete works
- US2: Hierarchical user data, query filtering, Redis cache
- US3: All endpoints work, main ≤100 lines, route files ≤100 lines
**Suggested MVP Scope**: Phase 1-4 (User Stories 1 + 2) = 98 tasks
**Format Validation**: ✅ ALL tasks follow checklist format (checkbox, ID, labels, file paths)
---
## Notes
- [P] tasks = different files, no dependencies
- [Story] label maps task to specific user story for traceability
- Each user story should be independently completable and testable
- Verify tests fail before implementing
- Commit after each task or logical group
- Stop at any checkpoint to validate story independently
- US1 and US2 are both P1 priority but US2 depends on US1
- Avoid: vague tasks, same file conflicts, cross-story dependencies that break independence
