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

Previously the /v1/usage endpoint aggregated usage stats (today/total
tokens, cost, RPM/TPM) across all API Keys belonging to the user.
This made it impossible to distinguish usage from different API Keys
(e.g. balance vs subscription keys).

Now the usage stats are filtered by the current request's API Key ID,
so each key only sees its own usage data. The balance/remaining fields
are unaffected and still reflect the user-level wallet balance.

Changes:
- Add GetAPIKeyDashboardStats to repository interface and implementation
- Add getPerformanceStatsByAPIKey helper (also fixes TPM to include
  cache_creation_tokens and cache_read_tokens)
- Add GetAPIKeyDashboardStats to UsageService
- Update Usage handler to call GetAPIKeyDashboardStats(apiKey.ID)

- Add missing IncrementQuotaUsed method to stubApiKeyRepo in api_contract_test.go
- Fix gofmt formatting issues in api_key_service.go, dto/types.go, api_key_handler.go

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

Add ListByUserPaginated and SumPositiveBalanceByUser to redeemRepoStub
Add GetUserBalanceHistory to stubAdminService

Fixes CI test compilation errors

- 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

- 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

- 新增 CalculateCostWithLongContext 方法支持阈值双倍计费
- 新增 RecordUsageWithLongContext 方法专用于 Gemini 计费
- Gemini 超过 200K token 的部分按 2 倍费率计算
- 其他平台（Claude/OpenAI）完全不受影响

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。

将账户停用 (USER_INACTIVE) 导致的请求失败视为业务限制类错误，不计入 SLA 和错误率统计。

账户停用是预期内的业务结果，不应被视为系统错误或服务质量问题。此改动使错误分类更加准确，避免将预期的业务限制误报为系统故障。

修改内容：
- 在 classifyOpsIsBusinessLimited 函数中添加 USER_INACTIVE 错误码
- 该类错误不再触发错误率告警

Fixes Wei-Shaw/sub2api#453

为 CC Switch 集成增强 /v1/usage 网关端点，在保持原有 4 字段
(isValid, planName, remaining, unit) 向后兼容的基础上，新增：

- usage 对象：今日/累计的请求数、token 用量、费用，以及 RPM/TPM
- subscription 对象（订阅模式）：日/周/月用量和限额、过期时间
- balance 字段（余额模式）：当前钱包余额

用量数据获取采用 best-effort 策略，失败不影响基础响应。
