- Fix gofmt alignment in admin_service.go and trailing newline in
  antigravity_credits_overages.go
- Suppress errcheck for fmt.Sscanf in client.go GetMinimumAmount

Remove SimulateClaudeMaxEnabled field and related logic from
admin_service.go, and remove applyClaudeMaxCacheBillingPolicyToUsage,
applyClaudeMaxNonStreamingRewrite, setupClaudeMaxStreamingHook calls
from antigravity_gateway_service.go. These symbols are not yet
available in upstream/main.

Replace process-memory sync.Map + per-model runtime state with a single
"AICredits" key in model_rate_limits, making credits exhaustion fully
isomorphic with model-level rate limiting.

Scheduler: rate-limited accounts with overages enabled + credits available
are now scheduled instead of excluded.

Forwarding: when model is rate-limited + credits available, inject credits
proactively without waiting for a 429 round trip.

Storage: credits exhaustion stored as model_rate_limits["AICredits"] with
5h duration, reusing SetModelRateLimit/isRateLimitActiveForKey.

Frontend: show credits_active (yellow ⚡) when model rate-limited but
credits available, credits_exhausted (red) when AICredits key active.

Tests: add unit tests for shouldMarkCreditsExhausted, injectEnabledCreditTypes,
clearCreditsExhausted, and update existing overages tests.

feat: implement resolveCreditsOveragesModelKey function to stabilize model key resolution for credit overages

feat(ops): add ignore insufficient balance errors toggle and extract error constants

fix: 修复多个issues - Gemini schema 兼容性、批量编辑白名单、Docker 工具支持和限额字段处理Fix/open issues cleanup

The upstream Gemini API returns "Insufficient account balance" which
doesn't contain the substring "insufficient balance". Add explicit
match for the full phrase to ensure the filter works correctly.

commit 0debe0a8 在修复 OpenAI WS 用量窗口刷新问题时，意外删除了
UsageProgressBar 中的 window stats 渲染逻辑和格式化函数。

恢复进度条上方的统计行（requests, tokens, account cost, user cost）
及对应的 4 个格式化 computed 属性。

修复批量编辑账号时，UI 显示的是 plain 模型名（如 GPT-5），但实际落库的是 dated 模型名的问题。

核心改动：
1. 批量编辑白名单不再使用 BulkEditAccountModal.vue 中手写的过期模型列表
   - 移除了 allModels 和 presetMappings 的硬编码列表（共 200+ 行）
   - 直接复用 ModelWhitelistSelector.vue 组件

2. ModelWhitelistSelector 组件支持多平台联合过滤
   - 新增 platforms 属性支持传入多个平台
   - 添加 normalizedPlatforms 计算属性统一处理单平台和多平台场景
   - availableOptions 根据选中的多个平台动态联合过滤模型列表
   - fillRelated 功能支持一次性填充多个平台的相关模型

3. 模型映射预设改为动态生成
   - filteredPresets 改用 getPresetMappingsByPlatform 从统一模型源按平台动态生成
   - 不再依赖弹窗中的手写预设列表

现在的行为：
- UI 显示什么模型，勾选什么模型，传给后端的就是什么模型
- 彻底解决了批量编辑链路上"显示与实际不一致"的问题
- 模型列表和映射预设始终与系统定义保持同步

为了支持容器内的数据库备份和恢复功能，在运行时镜像中添加 PostgreSQL 客户端工具。

变更内容：
- 使用多阶段构建从 postgres:18-alpine 镜像复制 pg_dump 和 psql 二进制文件
- 添加必要的依赖库（libpq, zstd-libs, lz4-libs, krb5-libs, libldap, libedit）
- 升级基础镜像到 alpine:3.21
- 复制 libpq.so.5 共享库以确保工具正常运行

这样可以在运行时容器中直接执行数据库备份和恢复操作，无需访问 Docker socket。

修复在填写限额时，如果不填写完整的三个限额额度（日限额、周限额、月限额）就会报错的问题。

变更内容：
- 后端：添加 optionalLimitField 类型处理空值和空字符串，兼容部分限额字段为空的情况
- 前端：添加 normalizeOptionalLimit 函数规范化限额输入，将空值、空字符串和无效数字统一处理为 null

Remove misleading "upstream" wording - the error is about client API key
user balance, not upstream account balance.

- Add 5th error filter switch IgnoreInsufficientBalanceErrors to suppress
  upstream insufficient balance / insufficient_quota errors from ops log
- Extract hardcoded error strings into package-level constants for
  shouldSkipOpsErrorLog, normalizeOpsErrorType, classifyOpsPhase, and
  classifyOpsIsBusinessLimited
- Define ErrNoAvailableAccounts sentinel error and replace all
  errors.New("no available accounts") call sites
- Update tests to use require.ErrorIs with the sentinel error

fix: extract and log Claude output_config.effort in usage records

feat: add endpoint metadata and usage endpoint distribution insights

fix(billing): treat nil rate limit window as expired to prevent usage accumulation

fix(billing): allow clearing group quota limits and treat 0 as zero-limit

fix(gateway): 防止流式 failover 拼接腐化导致客户端收到双 message_start fix issue #991

fix: Bedrock 账户配额限制不生效

Previously, v-model.number produced "" when input was cleared, causing
JSON decode errors on the backend. Also, normalizeLimit treated 0 as
"unlimited" which prevented setting a zero quota. Now "" is converted
to null (unlimited) in frontend, and 0 is preserved as a valid limit.

Closes Wei-Shaw/sub2api#1021

When Redis cache is populated from DB with a NULL window_1d_start, the
Lua increment script only updates usage counters without setting window
timestamps. IsWindowExpired(nil) previously returned false, so the
accumulated usage was never reset across time windows, effectively
turning usage_1d into a lifetime counter. Once this exceeded
rate_limit_1d the key was incorrectly blocked with "日限额已用完".

Fixes Wei-Shaw/sub2api#1022

Claude's output_config.effort parameter (low/medium/high/max) was not
being extracted from requests or logged in the reasoning_effort column
of usage logs. Only the OpenAI path populated this field.

Changes:
- Extract output_config.effort in ParseGatewayRequest
- Add ReasoningEffort field to ForwardResult
- Populate reasoning_effort in both RecordUsage and RecordUsageWithLongContext
- Guard against overwriting service-set effort values in handler
- Update stale comments that described reasoning_effort as OpenAI-only
- Add unit tests for extraction, normalization, and persistence

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。

当上游在 SSE 流中途返回 event:error 时，handleStreamingResponse 已将
部分 SSE 事件写入客户端，但原先的 failover 逻辑仍会切换到下一个账号
并写入完整流，导致客户端收到两个 message_start 进而产生 400 错误。

修复方案：在每次 Forward 调用前记录 c.Writer.Size()，若 Forward 返回
UpstreamFailoverError 后 writer 字节数增加，说明 SSE 内容已不可撤销地
发送给客户端，此时直接调用 handleFailoverExhausted 发送 SSE error 事件
终止流，而非继续 failover。

Ping-only 场景不受影响：slot 等待期的 ping 字节在 Forward 前后相等，
正常 failover 流程照常进行。

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。

后端默认 alert.enabled=true 但 recipients 为空，前端验证将其视为
错误并阻断保存按钮。移除该阻断性验证，改为保存时自动禁用无收件人
的邮件通知配置。

将独立的 /admin/backup 和 /admin/data-management 页面整合到设置页，
作为「备份」和「Sora 存储」标签页，减少侧边栏条目，集中管理配置。

- 移除 BackupView 和 DataManagementView 的 AppLayout 包装
- 在 SettingsView 中以子组件形式嵌入，使用 v-show 切换标签
- 删除独立路由和侧边栏菜单入口
- 备份/数据标签页下隐藏主保存按钮（各自有独立保存）
- 优化标签栏样式适配7个标签，PC端支持细滚动条
- 清理未使用的图标组件和 i18n 键
