refactor: 五层对齐 22 表 + 工具并入 agent/ + 支付适配器内联（路由零变更）

- service/dto/controller 各拆 18 文件，一表一文件；跨表编排留在 outfit_generation_task_service
- controller 共享 struct（outfit/member）保 /outfit/*、/member/* 前缀，路由零漂移（28 路径 diff 为空）
- 修复 4 个缺失 g.Meta handler：/user/profile、/avatar/get、/body-measurement/get、/hairstyle/list 从 ALL 收敛为 GET
- 工具包并入 agent/ 单包（weather/imagegen/avatar/scoring），NewCache 泛化 NewTTLCache
- 虎皮椒支付适配器内联 service/payment_order_service.go，member 服务拆 4 表文件
- 冒烟 21 路径全绿 + 客户端 dart analyze 零 error
