feat(redeem): support subscription type in create-and-redeem API

Add group_id and validity_days fields to CreateAndRedeemCodeRequest,
enabling subscription-type redemption codes to be created and redeemed
in a single API call.

- Type defaults to "balance" when omitted for backward compatibility
- Subscription type requires group_id (non-nil) and validity_days (>0)
- Existing balance/concurrency callers are unaffected

feat(groups): add rate multipliers management modal

fix: 管理员重置配额补全 monthly 字段并修复 ristretto 缓存异步问题 fix issue #964

- 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

feat: GPT Private设置数据不用于训练

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。

Feature/管理员可以重置账号额度

将 /v1/chat/completions 端点从 ResponseWriter 劫持模式重构为独立的
类型安全转换路径，与 Anthropic Messages 端点架构对齐：

- 在 apicompat 包新增 Chat Completions 完整类型定义和双向转换器
- 新增 ForwardAsChatCompletions service 方法，走 Responses API 上游
- Handler 改为独立的账号选择/failover 循环，不再劫持 Responses handler
- 提取 handleCompatErrorResponse 为 Chat Completions 和 Messages 共用
- 删除旧的 forwardChatCompletions 直传路径及相关死代码

Anthropic Messages API 的流式转发路径（gateway_service.go）在上游长时间
无数据时（如 Opus extended thinking 阶段）不会向下游发送任何内容，导致
Cloudflare Tunnel 等代理因连接空闲而断开。

复用已有的 StreamKeepaliveInterval 配置（默认 10 秒），在 select 循环中
添加 keepalive 分支，定时发送 Anthropic 原生格式的 ping 事件保活，与
OpenAI 兼容路径的实现模式保持一致。
