DaydreamCoding 6b39b344d8 feat(quota): 用户 × 平台 USD 配额
为用户在 anthropic/openai/gemini/antigravity 四个平台上提供日/周/月
三个窗口的 USD 配额管控。配额语义:未设置=不限制,0=禁用,>0=美元上限。

两层模型:
- 配置层:系统默认配额,以及 email/linuxdo/oidc/wechat/github/google/
  dingtalk 七个鉴权来源的默认配额,存于 settings,以嵌套 JSON 整体读写
  (系统 1 个 key + 每个来源 1 个 key),整体替换语义。
- 运行时层:user_platform_quota 表按用户记录实际配额,与配置层解耦。

后端:新增 ent schema 与 140_user_platform_quotas.sql 迁移、repository
与 service 端口、计费链路集成、管理端与用户端读写接口。
前端:管理端设置页配额编辑、用户配额管理 Modal、用户 Dashboard 展示、
中英文案。
