Consolidate two separate channel types (bedrock + bedrock-apikey) into
a single "AWS Bedrock" channel. Authentication mode is now distinguished
by credentials.auth_mode ("sigv4" | "apikey") instead of separate types.

Backend:
- Remove AccountTypeBedrockAPIKey constant
- IsBedrock() simplified; IsBedrockAPIKey() checks auth_mode
- Add IsAPIKeyOrBedrock() helper to eliminate repeated type checks
- Extend pool mode, quota scheduling, and billing to bedrock
- Add RetryableOnSameAccount to handleBedrockUpstreamErrors
- Add "bedrock" scope to Beta Policy for independent control

Frontend:
- Merge two buttons into one "AWS Bedrock" with auth mode radio
- Badge displays "Anthropic | AWS"
- Pool mode and quota limit UI available for bedrock
- Quota display in account list (usage bars, capacity badges, reset)
- Remove all bedrock-apikey type references

Backend:
- Detect and classify 403 responses into three types:
  validation (account needs Google verification),
  violation (terms of service / banned),
  forbidden (generic 403)
- Extract verification/appeal URLs from 403 response body
  (structured JSON parsing with regex fallback)
- Add needs_verify, is_banned, needs_reauth, error_code fields
  to UsageInfo (omitempty for zero impact on other platforms)
- Handle 403 in request path: classify and permanently set account error
- Save validation_url in error_message for degraded path recovery
- Enrich usage with account error on both success and degraded paths
- Add singleflight dedup for usage requests with independent context
- Differentiate cache TTL: success/403 → 3min, errors → 1min
- Return degraded UsageInfo instead of HTTP 500 on quota fetch errors

Frontend:
- Display forbidden status badges with color coding (red for banned,
  amber for needs verification, gray for generic)
- Show clickable verification/appeal URL links
- Display needs_reauth and degraded error states in usage cell
- Add Antigravity tier label badge next to platform type

Tests:
- Comprehensive unit tests for classifyForbiddenType (7 cases)
- Unit tests for extractValidationURL (8 cases including unicode escapes)
- Integration test for FetchQuota forbidden path

- 后端新增 rolling/fixed 两种配额重置模式，支持日配额和周配额
- fixed 模式下可配置重置时刻（小时）、重置星期几（周配额）及时区（IANA）
- 在 account_repo.go 中使用 SQL 表达式适配两种模式的过期判断与重置时间推进
- 新增 ComputeQuotaResetAt / ValidateQuotaResetConfig 等辅助函数
- DTO 层新增相关字段并在 mappers 中完整映射
- 前端 QuotaLimitCard 新增 rolling/fixed 切换 UI、时区选择器
- CreateAccountModal / EditAccountModal 透传新配置字段
- i18n（zh/en）同步新增相关翻译词条

- 后端 handler：ResetSubscriptionQuotaRequest 新增 Monthly 字段，
  验证逻辑扩展为 daily/weekly/monthly 至少一项为 true
- 后端 service：AdminResetQuota 新增 resetMonthly 参数，
  调用 ResetMonthlyUsage；重置后追加 subCacheL1.Wait()，
  保证 ristretto Del() 的异步删除立即生效，消除重置后
  /v1/usage 返回旧用量数据的竞态窗口
- 后端测试：更新存量测试用例匹配新签名，补充
  TestAdminResetQuota_ResetMonthlyOnly /
  TestAdminResetQuota_ResetMonthlyUsageError 两个新用例
- 前端 API：resetQuota options 类型新增 monthly: boolean
- 前端视图：confirmResetQuota 改为同时重置 daily/weekly/monthly
- i18n：中英文确认提示文案更新，提及每月配额

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

- Add AdminResetQuota service method to reset daily/weekly usage windows
- Add POST /api/v1/admin/subscriptions/:id/reset-quota handler and route
- Add resetQuota API function in frontend subscriptions client
- Add reset quota button, confirmation dialog, and handlers in SubscriptionsView
- Add i18n keys for reset quota feature in zh and en locales

1. 识别OpenAI "An error occurred while processing your request" 临时性400错误
   并触发failover，同时在池模式下标记RetryableOnSameAccount，允许同账号重试
2. ForwardAsAnthropic路径同步支持临时性400错误的识别和同账号重试
3. HelpTooltip组件使用Teleport渲染到body，修复在dialog内被裁切的问题

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

QuotaBadge components (daily/weekly/total) were wrapped in a
horizontal flex container, making them visually inconsistent with
other capacity badges (concurrency, window cost, sessions, RPM)
which stack vertically. Remove the wrapper so all badges align
consistently.

Embedded pages (purchase subscription, custom pages) now receive the
current user locale through a `lang` URL parameter, allowing iframe
content to match the user's language preference.
