refactor: Antigravity/Codex 服务重构为插件化适配器架构

- 将 Antigravity 和 Codex 从独立模块迁移至 src/services/provider/adapters/ 插件体系
- 新增 provider_types 和 oauth_token 模块，移除 maintenance_scheduler 中的 OAuth 定时刷新
- 增强 admin API：扩展 keys 和 provider_query 端点，新增 dashboard 路由
- 大幅增强 ProviderDetailDrawer 组件，新增 AntigravityQuotaDialog
- 改进 handler 基类（chat/cli）和错误分类器
- 优化 fetch_scheduler 和 upstream_fetcher
- 前端 UI 组件清理和优化
- 更新测试以匹配新模块结构
