feat(phase5): 解耦与收尾清理

- core/redis_client.py 移除 scheduler 耦合，lifespan 由 core/app.py 组合（Redis→调度器→Redis）
- main.py 改从 core.app 导入 create_app
- 删除 apps/、extensions/ 目录；utils 删除已迁移垫片与死代码 formatter.py
- 新增 deploy/（nginx、supervisor）、scripts/（init_db、seed）、logs/（结构化日志落盘）
- core/app.py 接入 core.logger setup_logging
- 更新 CLAUDE.md 反映 core/shared/modules 新结构

+数据库初始化脚本
+=============================================================
+
+功能：
+1. 创建数据库（默认 utf8mb4）
+2. 导入 document/djangoadmin.fastapi.elevue.sql（若存在）
+3. 用模型 metadata 补建 SQL 中缺失的表（如 fastapi_login_log / fastapi_operation_log）
+
+用法：
+    python scripts/init_db.py                     # 使用 .env 中的数据库配置
+    python scripts/init_db.py --drop-first         # 先删除已存在的同名库再重建
