Move constants, detection, and penalty functions from
antigravity_gateway_service.go to antigravity_internal500_penalty.go.
Fix gofmt alignment and replace hardcoded duration strings with
constant references.

When an antigravity account returns 500 "Internal error encountered."
on all 3 retry attempts, increment a Redis counter and apply escalating
penalties:
- 1st round: temp unschedulable 10 minutes
- 2nd round: temp unschedulable 10 hours
- 3rd round: permanently mark as error

Counter resets on any successful response (< 400).

## Problem

When a proxy is unreachable, token refresh retries up to 4 times with
30s timeout each, causing requests to hang for ~2 minutes before
failing with a generic 502 error. The failed account is not marked,
so subsequent requests keep hitting it.

## Changes

### Proxy connection fast-fail
- Set TCP dial timeout to 5s and TLS handshake timeout to 5s on
  antigravity client, so proxy connectivity issues fail within 5s
  instead of 30s
- Reduce overall HTTP client timeout from 30s to 10s
- Export `IsConnectionError` for service-layer use
- Detect proxy connection errors in `RefreshToken` and return
  immediately with "proxy unavailable" error (no retries)

### Token refresh temp-unschedulable
- Add 8s context timeout for token refresh on request path
- Mark account as temp-unschedulable for 10min when refresh fails
  (both background `TokenRefreshService` and request-path
  `GetAccessToken`)
- Sync temp-unschedulable state to Redis cache for immediate
  scheduler effect
- Inject `TempUnschedCache` into `AntigravityTokenProvider`

### Account failover
- Return `UpstreamFailoverError` on `GetAccessToken` failure in
  `Forward`/`ForwardGemini` to trigger handler-level account switch
  instead of returning 502 directly

### Proxy probe alignment
- Apply same 5s dial/TLS timeout to shared `httpclient` pool
- Reduce proxy probe timeout from 30s to 10s

- 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

从上游 /v1/messages 响应头被动采集 5h/7d utilization 并存储到
Account.Extra，页面加载时直接读取本地数据而非调用外部 Usage API。
用户可点击"查询"按钮主动拉取最新数据，主动查询结果自动回写被动缓存。

后端:
- UpdateSessionWindow 合并采集 5h + 7d headers 为单次 DB 写入
- 新增 GetPassiveUsage 从 Extra 构建 UsageInfo (复用 estimateSetupTokenUsage)
- GetUsage 主动查询后 syncActiveToPassive 回写被动缓存
- passive_usage_ 前缀注册为 scheduler-neutral

前端:
- Anthropic 账号 mount/refresh 默认 source=passive
- 新增"被动采样"标签和"查询"按钮 (带 loading 动画)

复用 GroupCapacityService，在 admin 分组列表中添加容量列，
显示每个分组的实时并发/会话/RPM 使用量和上限。
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

分组管理列表增强：

1. 今日/累计用量列：
   - 新增独立端点 GET /admin/groups/usage-summary
   - 一次查询返回所有分组的今日费用和累计费用（actual_cost）
   - 前端异步加载后合并显示在分组列表中

2. 账号数区分可用/限流/总量：
   - 将账号数列从单一总量改为 badge 内多行展示
   - 可用: active + schedulable 的账号数（绿色）
   - 限流: rate_limit/overload/temp_unschedulable 的账号数（橙色，无限流时隐藏）
   - 总量: 全部关联账号数

Add a platform filter dropdown to the admin subscriptions view, allowing
filtering subscriptions by platform (Anthropic, OpenAI, Gemini, etc.)
through the group association.

Cover IsValidModelSource/NormalizeModelSource, resolveModelDimensionExpression SQL expressions, invalid model_source 400 responses on both GetModelStats and GetUserBreakdown, upstream_model in scan/insert SQL mock expectations, and updated passthrough/billing test signatures.

Support querying model statistics by 'requested', 'upstream', or 'mapping' dimension. Add resolveModelDimensionExpression for safe SQL expression generation, IsValidModelSource whitelist validator, and NormalizeModelSource fallback. Repository persists and scans upstream_model in all insert/select paths.

Handler tests (9 cases): group_id/model/endpoint filters, default
endpoint_type, custom limit, limit clamping, response format,
empty result, no-filter pass-through.

Repository test: resolveEndpointColumn mapping for inbound/upstream/path.

Click on a group name, model name, or endpoint name in the distribution
tables to expand and show per-user usage breakdown (requests, tokens,
actual cost, standard cost).

Backend: new GET /admin/dashboard/user-breakdown API with group_id,
model, endpoint, endpoint_type filters.
Frontend: clickable rows with expand/collapse sub-table in all three
distribution charts.

POST /backups 和 POST /backups/:id/restore 改为异步：立即返回 HTTP 202，
后台 goroutine 独立执行 pg_dump → gzip → S3 上传，前端每 2s 轮询状态。

后端:
- 新增 StartBackup/StartRestore 方法，后台 goroutine 不依赖 HTTP 连接
- Graceful shutdown 等待活跃操作完成，启动时清理孤立 running 记录
- BackupRecord 新增 progress/restore_status 字段支持进度和恢复状态追踪

前端:
- 创建备份/恢复后轮询 GET /backups/:id 直到完成或失败
- 标签页切换暂停/恢复轮询，组件卸载清理定时器
- 正确处理 409（备份进行中）和轮询超时

The updateRateLimitUsageScript Lua script previously performed
unconditional HINCRBYFLOAT on all usage counters without checking
whether the rate limit window had expired. This caused usage to
accumulate across window boundaries in Redis while the DB correctly
reset on expiration, leading to incorrect 429 rate limiting that
could persist for up to 24 hours.

The Lua script now checks each window timestamp before incrementing:
- If the window has expired, usage is reset to the current cost and
  the window timestamp is updated (matching DB-side semantics)
- If the window is still valid, usage is accumulated normally

This also resolves the async race condition where stale HINCRBYFLOAT
tasks from the worker queue could pollute a freshly rebuilt cache
after invalidation, since the script now self-corrects expired windows.

Closes #1049

Replace t.Add(24*time.Hour - time.Nanosecond) with t.AddDate(0, 0, 1) and use SQL < instead of <= for end-of-day boundaries. This avoids edge-case misses around DST transitions.

将入站、上游与路径三类端点分布统一到使用记录页的一致化卡片交互中，并补齐端点元数据与统计链路，提升排障与流量分析效率。

applyUsageBillingEffects() 中配额更新条件仅检查了 AccountTypeAPIKey，
遗漏了 AccountTypeBedrock，导致 Bedrock 账户的配额计数器永远不递增。
扩展条件以同时支持 APIKey 和 Bedrock 类型。

同时在前端账户筛选下拉框中添加 AWS Bedrock 选项。

1. S3 凭证加密存储：使用 SecretEncryptor (AES-256-GCM) 加密 SecretAccessKey，
   防止备份文件中泄露 S3 凭证，兼容旧的未加密数据
2. 修复 saveRecord 竞态条件：添加 recordsMu 互斥锁保护 records 的 load/save
3. 恢复操作增加服务端验证：handler 层要求重新输入管理员密码，通过 bcrypt
   校验，前端弹出密码输入框
4. pg_dump/psql/S3 操作抽象为接口：定义 DBDumper 和 BackupObjectStore 接口，
   实现放入 repository 层，遵循项目依赖注入架构规范
5. 改为流式处理避免大数据库 OOM：备份时 pg_dump stdout -> gzip -> io.Pipe ->
   S3 upload；恢复时 S3 download -> gzip reader -> psql stdin，不再全量加载
6. loadRecords 区分"无数据"和"数据损坏"场景：JSON 解析失败返回明确错误
7. 添加 18 个核心逻辑单元测试：覆盖加密、并发、流式备份/恢复、错误处理等

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
