feat(admin): Add group filtering for account listings

gosec -conf 只支持 JSON 格式，将 .gosec.yaml 转换为 .gosec.json

chore: 配置 gosec 排除规则

- 新增 backend/.gosec.yaml 配置文件，排除 G704 (SSRF) 检查
- 更新 security-scan.yml workflow，使用 gosec 配置文件
- 原因：作为 API 网关平台，需要代理请求到配置的上游服务，所有上游 URL 来自管理员配置而非用户输入

- Add groupID parameter to ListAccounts and ListWithFilters methods
- Implement account filtering by group ID in repository query
- Add group query parameter parsing in account handler
- Update all ListAccounts/ListWithFilters call sites with groupID parameter
- Add group filter UI component to AccountTableFilters
- Add i18n translations for group filter label in English and Chinese
- Update API contract and test stubs to reflect new signature
- Enable filtering accounts by their assigned groups in admin panel

fix: 修复登录/注册页面自定义 Logo 不显示及闪烁问题

feat(admin): 为账户和兑换码新增邮箱搜索及限流过滤功能

[UPDATE] 增强 Claude Thinking 模式支持与 Opus 4.6 动态预算适配

feat(antigravity): 支持 Refresh Token 批量导入创建 OAuth 账号

fix: include Gemini thoughtsTokenCount in output token billing

- sanitizeUrl 新增 allowDataUrl 选项，支持 data:image/ 格式的 base64 图片 URL
- AuthLayout 改用 appStore 缓存数据，避免重复 API 请求和默认 Logo 闪烁

- Add used_by_email column to redeem code export CSV for better user identification
- Implement rate_limited status filter in account listing with RateLimitResetAt check
- Extend redeem code search to include user email in addition to code matching
- Add API key search capability to user listing filters
- Display user email in redeem code table used_by column for improved visibility
- Update search placeholders in UI to reflect expanded search capabilities (email, username, notes, API key)
- Improve Chinese and English localization strings for search hints

Gemini 2.5 Pro/Flash thinking models return thoughtsTokenCount separately
from candidatesTokenCount in usageMetadata, but this field was not parsed
or included in billing calculations, causing thinking tokens to be
unbilled.

- Add ThoughtsTokenCount field to GeminiUsageMetadata struct
- Include thoughtsTokenCount in OutputTokens across all 3 Gemini usage
  parsing paths (non-streaming, streaming, compat layer)
- Add tests covering thinking token scenarios

Closes #554

feat(antigravity): 添加 onboardUser 支持，修复 project_id 缺失问题

- 新增 OnboardUser API 客户端方法，支持账号 onboarding 获取 project_id
- loadProjectIDWithRetry 增加 onboard 回退：LoadCodeAssist 未返回 project_id 时自动触发 onboarding
- GetAccessToken 中 project_id 补齐改用轻量 FillProjectID 替代全量 RefreshAccountToken
- 补齐逻辑增加 5 分钟冷却机制，防止频繁重试
- OnboardUser 轮询等待改为 context 感知，支持提前取消
- 提取 mergeCredentials 辅助方法消除重复代码
- 新增 extractProjectIDFromOnboardResponse 和 resolveDefaultTierID 单元测试

🧠 refactor(antigravity): 完善 thinking 预算分配策略并重构工具构建逻辑

✨ feat(antigravity): 支持 thinking adaptive 类型并适配 Opus 4.6 动态预算
🧪 test(gateway): 增加 thinking 模式解析与签名块过滤的边界用例测试

后端新增 ValidateRefreshToken service 方法和 POST /oauth/refresh-token 端点，
前端新增 API/Composable/UI 集成，OAuthAuthorizationFlow i18n 动态化，
支持在 Antigravity 创建账号时批量粘贴 Refresh Token 自动验证并创建账号。

feat: 错误处理增强、重试优化与性能改进

- gofmt: 修复 error_passthrough_service.go 格式问题
- errcheck: 修复 error_passthrough_runtime_test.go 类型断言未检查
- staticcheck: if-else 改为 switch (gateway_service.go)
- test: 修复两个测试用例错误使用 MODEL_CAPACITY_EXHAUSTED 导致走错路径

- MatchRule 延迟/限制 body ToLower，先用 statusCode 短路，只在需要关键词匹配时转换且限制 8KB
- 预计算规则的小写关键词/平台和 error code set，消除运行时重复 ToLower 和线性扫描
- MODEL_CAPACITY_EXHAUSTED 全局去重，避免并发请求重复重试同一模型
- 503 重试 body 读取限制从 2MB 降至 8KB
- time.After 替换为 time.NewTimer，防止 context 取消时 timer 泄漏

- ops_error_logger: status < 400 分支增加 OpsSkipPassthroughKey 检查
- ops_upstream_context: 新增 checkSkipMonitoringForUpstreamEvent，中间重试/故障转移事件也能触发跳过标记
- gateway_handler/openai_gateway_handler/gemini_v1beta_handler: handleFailoverExhausted 匹配规则后设置 OpsSkipPassthroughKey
- antigravity_gateway_service: writeMappedClaudeError 增加 applyErrorPassthroughRule 调用

feat(antigravity): 转发与测试支持 daily/prod 单 URL 切换

合并上游新增的 Antigravity 单账号 503 退避重试机制，
解决与本地 MODEL_CAPACITY_EXHAUSTED 逻辑的冲突，两者共存。

在每条错误透传规则上新增 skip_monitoring 选项，开启后匹配该规则的错误
不会被记录到 ops_error_logs，减少监控噪音。默认关闭，不影响现有规则。

feat: Antigravity 单账号分组 503 退避重试机制

MODEL_CAPACITY_EXHAUSTED (503) 表示模型容量不足，所有账号共享同一容量池，
切换账号无意义。改为固定1s间隔重试最多60次，重试耗尽后直接返回上游错误。

- 新增 antigravityModelCapacityRetryMaxAttempts=60 和 antigravityModelCapacityRetryWait=1s
- shouldTriggerAntigravitySmartRetry 新增 isModelCapacityExhausted 返回值
- handleSmartRetry 对 MODEL_CAPACITY_EXHAUSTED 使用独立重试策略
- handleModelRateLimit 对 MODEL_CAPACITY_EXHAUSTED 仅标记 Handled，不设限流
- 重试耗尽后不设置模型限流、不清除粘性会话、不切换账号

For retryable transient errors (Google 400 "invalid project resource name"
and empty stream responses), retry on the same account up to 2 times
(with 500ms delay) before switching to another account.

- Add RetryableOnSameAccount field to UpstreamFailoverError
- Add same-account retry loop in both Gemini and Claude/OpenAI handler paths
- Move temp-unschedule from service layer to handler layer (only after
  all same-account retries exhausted)
- Reduce temp-unschedule cooldown from 30 minutes to 1 minute

- Empty stream responses now return UpstreamFailoverError instead of
  plain 502, triggering automatic account switching (up to 10 retries)
- Add tempUnscheduleEmptyResponse: accounts returning empty responses
  are temp-unscheduled for 30 minutes
- Apply to both Claude and Gemini non-streaming paths
- Align googleConfigErrorCooldown from 60m to 30m for consistency

Google 后端间歇性返回 400 "Invalid project resource name" 错误，
此前该错误直接透传给客户端且不触发账号切换，导致请求失败。

- 在 Antigravity 和 Gemini 两个平台的所有转发路径中，
  精确匹配该错误消息后触发 failover 自动换号重试
- 命中后将账号临时封禁 1 小时，避免反复调度到同一故障账号
- 提取共享函数 isGoogleProjectConfigError / tempUnscheduleGoogleConfigError
  消除跨 Service 的代码重复

覆盖 Service 层和 Handler 层的所有新增逻辑：
- isSingleAccountRetry context 标记检查
- handleSmartRetry 中 503 + SingleAccountRetry 分支
- handleSingleAccountRetryInPlace 原地重试逻辑
- antigravityRetryLoop 预检查跳过限流
- sleepAntigravitySingleAccountBackoff 固定延迟退避
- 端到端集成场景验证

fix: support clearing model-level rate limits from action menu and temp-unsched reset

fix: Gemini error policy check should precede retry logic
