- gofmt: 修复 admin_service/antigravity_oauth_service/token_refresh_service 格式
- staticcheck S1009: 移除 SetUserSettingsResponse.IsSuccess 中冗余的 nil 检查
- unused: 将仅测试使用的 applyAntigravitySubscriptionResult 移至测试文件

Made-with: Cursor

新增 Antigravity OAuth 隐私设置能力，在账号创建、刷新、导入和后台
Token 刷新路径自动调用 setUserSettings + fetchUserInfo 关闭遥测；
持久化后同步内存 Extra，错误处理改为日志记录。

Made-with: Cursor

- 新增分组列：展示用户的专属/公开分组，支持 hover 查看详情
- 新增分组筛选：下拉选择或模糊搜索分组名过滤用户
- 专属分组替换：点击专属分组弹出操作菜单，选择目标分组后
  自动授予新分组权限、迁移绑定的 Key、移除旧分组权限
- 后端新增 POST /admin/users/:id/replace-group 端点，事务内
  完成分组替换并失效认证缓存

UpdateAccount previously required len(input.Extra) > 0, causing explicit
empty payloads (extra:{}) to be silently skipped. Change condition to
input.Extra != nil so clearing quota keys actually persists.

- Fix gofmt alignment in admin_service.go and trailing newline in
  antigravity_credits_overages.go
- Suppress errcheck for fmt.Sscanf in client.go GetMinimumAmount

Remove SimulateClaudeMaxEnabled field and related logic from
admin_service.go, and remove applyClaudeMaxCacheBillingPolicyToUsage,
applyClaudeMaxNonStreamingRewrite, setupClaudeMaxStreamingHook calls
from antigravity_gateway_service.go. These symbols are not yet
available in upstream/main.

Replace process-memory sync.Map + per-model runtime state with a single
"AICredits" key in model_rate_limits, making credits exhaustion fully
isomorphic with model-level rate limiting.

Scheduler: rate-limited accounts with overages enabled + credits available
are now scheduled instead of excluded.

Forwarding: when model is rate-limited + credits available, inject credits
proactively without waiting for a 429 round trip.

Storage: credits exhaustion stored as model_rate_limits["AICredits"] with
5h duration, reusing SetModelRateLimit/isRateLimitActiveForKey.

Frontend: show credits_active (yellow ⚡) when model rate-limited but
credits available, credits_exhausted (red) when AICredits key active.

Tests: add unit tests for shouldMarkCreditsExhausted, injectEnabledCreditTypes,
clearCreditsExhausted, and update existing overages tests.

feat: implement resolveCreditsOveragesModelKey function to stabilize model key resolution for credit overages

Previously, v-model.number produced "" when input was cleared, causing
JSON decode errors on the backend. Also, normalizeLimit treated 0 as
"unlimited" which prevented setting a zero quota. Now "" is converted
to null (unlimited) in frontend, and 0 is preserved as a valid limit.

Add a dedicated modal in group management for viewing, adding, editing,
and deleting per-user rate multipliers within a group.

Backend:
- GET /admin/groups/:id/rate-multipliers - list entries with user details
- PUT /admin/groups/:id/rate-multipliers - batch sync (full replace)
- DELETE /admin/groups/:id/rate-multipliers - clear all entries
- Repository: GetByGroupID, SyncGroupRateMultipliers methods on
  user_group_rate_multipliers table (same table as user-side rates)

Frontend:
- New GroupRateMultipliersModal component with:
  - User search and add with email autocomplete
  - Editable rate column with local edit mode (cancel/save)
  - Batch adjust: multiply all rates by a factor
  - Clear all (local operation, requires save to persist)
  - Pagination (10/20/50 per page)
  - Platform icon with brand colors in group info bar
  - Unsaved changes indicator with revert option
- Unit tests for all three backend endpoints

privacy_mode 改为由 TokenRefreshService 在 token 刷新后异步补设。

之前管理员无法通过 API 密钥管理将用户绑定到订阅类型分组（直接返回错误）。
现在改为检查用户是否持有该分组的有效订阅，有则允许绑定，无则拒绝。

- admin_service: 新增 userSubRepo 依赖，替换硬拒绝为订阅校验
- admin_service: 区分 ErrSubscriptionNotFound 和内部错误，避免 DB 故障被误报
- wire_gen/api_contract_test: 同步新增参数
- UserApiKeysModal: 管理员分组下拉不再过滤订阅类型分组

- 为定时测试计划增加 auto_recover 配置，补齐前后端类型、接口、仓储与数据库迁移
- 在定时测试成功后自动恢复账号 error、rate-limit 等可恢复运行时状态
- 新增 /admin/accounts/:id/recover-state 接口，合并原有重置状态与清限流操作
- 更新账号管理菜单与定时测试面板，补充自动恢复开关、说明提示和状态展示
- 补充账号恢复、限流清理与仓储同步相关测试

Extend the existing total quota limit with daily and weekly periodic
dimensions. Each dimension is independently configurable and uses lazy
reset — when the period expires, usage is automatically reset to zero on
the next increment. Any dimension exceeding its limit will pause the
account from scheduling.

Backend:
- Add GetQuotaDailyLimit/Used, GetQuotaWeeklyLimit/Used, HasAnyQuotaLimit
- Rewrite IncrementQuotaUsed with atomic CTE SQL for 3-dimension update
- Rewrite ResetQuotaUsed to clear all dimensions and period timestamps
- Update postUsageBilling to use HasAnyQuotaLimit()
- Preserve daily/weekly used values on account edit

Frontend:
- Refactor QuotaLimitCard from single v-model to 3-dimension props
- Add QuotaBadge component for compact D/W/$ display
- Update AccountCapacityCell with per-dimension badges
- Update Create/Edit modals with daily/weekly quota fields
- Update AccountActionMenu hasQuotaLimit to check all dimensions
- Add i18n strings for daily/weekly/total quota labels

chore: bump version to 0.1.90.4

提取 proxyurl.Parse() 公共包，将分散在 6 处的代理 URL 验证逻辑
统一收敛，确保无效代理配置在创建时立即失败，永不静默回退直连。

主要变更：
- 新增 proxyurl 包：统一 TrimSpace → url.Parse → Host 校验 → Scheme 白名单
- socks5:// 自动升级为 socks5h://，防止 DNS 泄漏（大小写不敏感）
- antigravity: http.ProxyURL → proxyutil.ConfigureTransportProxy 支持 SOCKS5
- openai_oauth: 删除 newOpenAIOAuthHTTPClient，收编至 httpclient.GetClient
- 移除未使用的 ProxyStrict 字段（fail-fast 已是全局默认行为）
- 补充 15 个 proxyurl 测试 + pricing/usage fail-fast 测试

- add default subscriptions to admin settings

- auto-assign subscriptions on register and admin user creation

- add validation/tests and align settings UI with subscription selector patterns

- BulkUpdate handler: add structured details to 409 response
- BulkUpdateAccounts: simplify to global pre-check before any DB write;
  remove per-account snapshot tracking which is no longer needed
- MixedChannelError.Error(): restore English message for API compatibility
- BulkEditAccountModal: use t() with details for both pre-check and 409
  fallback paths instead of displaying raw backend strings
- Update test to verify pre-check blocks on existing group conflicts

- Move mixed channel check before any DB writes in BulkUpdateAccounts
- Return 409 from BulkUpdate handler for MixedChannelError
- Add ConfirmDialog to BulkEditAccountModal for mixed channel warning

- 添加 HTTP PUT /api-keys/:id handler 端点，支持管理员直接修改 API Key 分组

## 事务一致性
- 使用 ent Tx 保证专属分组绑定时「添加权限」和「更新 Key」的原子性
- Repository 方法支持 clientFromContext，兼容事务内调用
- 事务失败时自动回滚，避免权限孤立

## 业务逻辑
- 订阅类型分组阻断，需通过订阅管理流程
- 非活跃分组拒绝绑定
- 负 ID 和非法 ID 验证
- 自动授权响应，告知管理员成功授权的分组

## 代码质量
- 16 个单元测试覆盖所有业务路径和边界用例
- 7 个 handler 集成测试覆盖 HTTP 层

- 新增 PUT /api/v1/admin/api-keys/:id 端点，允许管理员修改任意用户 API Key 的分组绑定
- 跳过用户级权限校验但保留分组有效性验证，修改后触发认证缓存失效
- Service 层支持三态语义：nil=不修改，0=解绑，>0=绑定，<0=拒绝
- 指针值拷贝保证安全隔离，负数 groupID 返回 400 INVALID_GROUP_ID
- 前端 UserApiKeysModal 新增可点击的分组选择下拉框，支持多 Key 并发更新
- 下拉支持视口翻转和滚动关闭，按钮有 disabled 和加载状态
- 覆盖：后端 20 个单元测试 (Service 11 + Handler 9) + 前端 16 个 E2E 测试

Add a dedicated CheckMixedChannel endpoint that allows the frontend
to pre-validate mixed channel risk before submitting create/update
requests. This improves UX by showing warnings earlier in the flow
instead of only after form submission.

Backend changes:
- Add CheckMixedChannelRequest struct and CheckMixedChannel handler
- Register POST /check-mixed-channel route
- Expose CheckMixedChannelRisk as public method on AdminService
- Simplify Create/Update 409 responses (remove details/require_confirmation)
- Add comprehensive handler tests and stub methods

Frontend changes:
- Add checkMixedChannelRisk API function and TypeScript types
- Refactor CreateAccountModal to precheck before step transition and submission
- Refactor EditAccountModal to precheck before update submission
- Replace pendingPayload pattern with action-based dialog flow
