refactor: 文件行数超标拆解（Service + Controller 9/16 完成）
- Service 层：energy_service → energize/operations/admin/query 四文件 - Service 层：post_service → helpers/audit + 核心 CRUD 保留 - Service 层：favorite_service → items + 核心文件夹操作保留 - Service 层：auth_service → password + 核心注册/登录保留 - Service 层：notification_service → notify + 核心列表/已读保留 - Service 层：audit_service → review + 核心列表/详情保留 - Controller 层：studio_controller → page/write/api/post_api/action 五文件 - Controller 层：post_controller → page/api/upload 三文件 - Controller 层：comment_controller → list/write/action/upload 四文件 - 清理未使用导入（notification_service.go 移除 fmt）
