Standardize filter bar layout across admin pages to place search/filters
on left and action buttons on right within the same row, improving
visual consistency and space utilization.

- avoid panic by using safe UUID prefix truncation in Gemini digest fallback logs\n- remove unconditional Antigravity 429 full-body debug logs and honor log truncation config\n- align Antigravity quick preset mappings to opus 4.6-thinking targets only\n- restore scope rate-limit aggregation/output in ops availability stats

1. Frontend: replace hardcoded antigravityDefaultMappings with async
   fetch from GET /admin/accounts/antigravity/default-model-mapping,
   eliminating the duplicate data source that caused frontend/backend
   mapping inconsistency.

2. Backend: convert handleSmartRetry and antigravityRetryLoop from
   standalone functions to AntigravityGatewayService methods, enabling
   Redis cache sync (updateAccountModelRateLimitInCache) after both
   rate-limit write paths — long-delay branch and retry-exhausted branch.

Key changes:
- Upgrade model mapping: Opus 4.5 → Opus 4.6-thinking with precise matching
- Unified rate limiting: scope-level → model-level with Redis snapshot sync
- Load-balanced scheduling by call count with smart retry mechanism
- Force cache billing support
- Model identity injection in prompts with leak prevention
- Thinking mode auto-handling (max_tokens/budget_tokens fix)
- Frontend: whitelist mode toggle, model mapping validation, status indicators
- Gemini session fallback with Redis Trie O(L) matching
- Ops: enhanced concurrency monitoring, account availability, retry logic
- Migration scripts: 049-051 for model mapping unification

Change formatTime() to include seconds (HH:MM:SS) instead of only
hours and minutes (HH:MM). This gives users more precise information
about when rate limits will reset.

- 将筛选器和操作按钮合并到同一行显示
- 筛选器在左侧，操作按钮在右侧
- 添加响应式支持，窄屏时自动换行并简化按钮文字

用户 Dashboard 的 Token 使用趋势图表现在显示 Input/Output/Cache 三种类型，
并在 Tooltip 中显示 Actual 和 Standard 价格，与管理员页面保持一致。

将 /api/health 改为 /health，与后端实际注册的路由一致

将错误透传规则按钮从自动刷新按钮前面移动到后面

支持管理员配置上游错误如何返回给客户端：
- 新增 ErrorPassthroughRule 数据模型和 Ent Schema
- 实现规则的 CRUD API（/admin/error-passthrough-rules）
- 支持按错误码、关键词匹配，支持 any/all 匹配模式
- 支持按平台过滤（anthropic/openai/gemini/antigravity）
- 支持透传或自定义响应状态码和错误消息
- 实现两级缓存（Redis + 本地内存）和多实例同步
- 集成到 gateway_handler 的错误处理流程
- 新增前端管理界面组件
- 新增单元测试覆盖核心匹配逻辑

优化：
- 移除 refreshLocalCache 中的冗余排序（数据库已排序）
- 后端 Validate() 增加匹配条件非空校验

- 新增 Access Token + Refresh Token 双令牌认证
- 支持 Token 自动刷新和轮转
- 添加登出和撤销所有会话接口
- 前端实现无感刷新和主动刷新定时器

This feature allows API Keys to have their own quota limits and expiration
times, independent of the user's balance.

Backend:
- Add quota, quota_used, expires_at fields to api_key schema
- Implement IsExpired() and IsQuotaExhausted() checks in middleware
- Add ResetQuota and ClearExpiration API endpoints
- Integrate quota billing in gateway handlers (OpenAI, Anthropic, Gemini)
- Include quota/expiration fields in auth cache for performance
- Expiration check returns 403, quota exhausted returns 429

Frontend:
- Add quota and expiration inputs to key create/edit dialog
- Add quick-select buttons for expiration (+7, +30, +90 days)
- Add reset quota confirmation dialog
- Add expires_at column to keys list
- Add i18n translations for new features (en/zh)

Migration:
- Add 045_add_api_key_quota.sql for new columns

- 后端 DTO 新增 scope_rate_limits 字段，从 extra 提取限流信息
- 前端状态列显示 scope 级限流徽章（Claude/Gemini/Image）
- 清除速率限制时同时清除账号级和 scope 级限流（已有实现）

Cherry-picked from slovx2/sub2api: 66f49b67

在运维监控的并发/排队卡片中，为 Antigravity 平台账号显示各 scope
(claude/gemini_text/gemini_image) 的限流数量统计，便于管理员了解
哪些 scope 正在被限流。

- 将 TLS Toggle 从第一步(PostgreSQL)移动到第二步(Redis)
- 添加缺失的 Toggle 组件导入

问题描述：
TLS 配置选项错误地出现在数据库配置步骤中，而不是 Redis 配置步骤

- Add new API endpoint GET /admin/users/:id/balance-history with pagination and type filter
- Add SumPositiveBalanceByUser for calculating total recharged amount
- Create UserBalanceHistoryModal component with:
  - User info header (email, username, created_at, current balance, notes, total recharged)
  - Type filter dropdown (all/balance/admin_balance/concurrency/admin_concurrency/subscription)
  - Quick deposit/withdraw buttons
  - Paginated history list with icons and colored values
- Add instant tooltip on balance column for better UX
- Add z-index prop to BaseDialog for modal stacking control
- Update i18n translations (zh/en)

- 创建分组时可选择从已有分组复制账号
- 编辑分组时支持同步账号（全量替换操作）
- 仅允许选择相同平台的源分组
- 添加完整的数据校验：去重、自引用检查、平台一致性检查
- 前端支持多选源分组，带提示说明操作行为

OpsAdvancedSettings 接口缺少 ignore_invalid_api_key_errors 字段，
导致 TypeScript 编译报错。

新增 IgnoreInvalidApiKeyErrors 开关，启用后 INVALID_API_KEY 和
API_KEY_REQUIRED 错误将被完全跳过，不写入 Ops 错误日志。
这些错误由用户错误配置导致，与服务质量无关。

- 为RedeemCode DTO添加notes字段（仅用于admin_balance/admin_concurrency类型）
- 更新mapper使其有条件地包含备注信息
- 在用户兑换历史UI中显示备注
- 备注以斜体显示，悬停时显示完整内容

用户现在可以看到管理员调整其余额的原因说明。

Changes:
- backend/internal/handler/dto/types.go: RedeemCode添加notes字段
- backend/internal/handler/dto/mappers.go: 条件性填充notes
- frontend/src/api/redeem.ts: TypeScript接口添加notes
- frontend/src/views/user/RedeemView.vue: UI显示备注信息

- 新增 AnnouncementBell 组件，支持 Modal 弹窗和 Markdown 渲染
- 移除 Dashboard 横幅和独立公告页面
- 铃铛位置在 Header 文档按钮左侧，显示未读红点
- 支持点击查看详情、标记已读、全部已读等操作
- 完善国际化，移除所有硬编码中文
- 修复 AnnouncementTargetingEditor watch 循环问题

Implements announcements end-to-end (admin CRUD + read status, user list + mark read) with OR-of-AND targeting. Also breaks the ent<->service import cycle by moving schema-facing constants/targeting into a new domain package.
