站点配置（百世密码/韵达账密/安能路径）从 config.yaml 移至 state.db

- state_store：加 site_settings(site,key,value) 表 + get_setting/set_setting/get_site_settings
- runtime：seed_legacy_config 启动一次性从 config.yaml 灌入（已存在不覆盖）；安能 app_path 改读 state_store
- site_baishi：导出密码改读 get_setting("百世","password")
- site_yunda：登录账密改读 get_setting("韵达",...)
- server：/config PUT 接受 settings；新增 GET /config/{site}/settings（不进 5s 轮询）

debug 仍保留在 config.yaml；站点配置现由前端配置弹窗管理（state.db 为准）。
