feat: Week 4 收尾 + 架构治理 — 搜索/家长中心/Feature Flag/Docker/环境配置

架构治理:
- Feature Flag 落地: Cargo.toml [features] default=["diary"] + main.rs cfg 条件编译
- 环境配置统一: AppConfig 类 + --dart-define 注入 + SSE 端口 8080→3000 修复

搜索替代方案 (无 FTS):
- SearchBloc + 标签/心情筛选接入后端 API
- JournalRepository 扩展 mood/tag 筛选参数
- 搜索页 UI 接入实际数据（替换占位文本）

家长中心最小集 (PIPL 合规):
- 后端: parent_service (绑定/查看/导出/删除/解绑) + parent_handler (6 个 API 端点)
- 前端: ParentBloc + ParentPage 功能完整实现
- 绑定孩子、只读查看日记、导出数据、删除数据、解绑

Docker 部署:
- verify.sh 健康检查脚本 (Axum/PG/Redis/OpenAPI 四项检查)

测试修复:
- home_bloc_test / calendar_bloc_test 适配 JournalRepository 新参数

验证: flutter test 84/84 pass, cargo test 76/76 pass, cargo check pass
