Revert payment/wechat, sora/claude-max cleanup, fork-only migrations,
and cosmetic changes that were brought in by the release sync commit.
Keep only channel-monitor related improvements:
- PublicSettingsInjectionPayload named struct with drift test
- ChannelMonitorRunner graceful shutdown in wire
- image_output_price in SupportedModelChip
- Simplified buildSelfNavItems in AppSidebar
- Gateway WARN logs for 503 branches

- Extract PublicSettingsInjectionPayload named struct with drift test
- Add channel_monitor_default_interval_seconds to SSR injection
- Add image_output_price to SupportedModelChip
- Simplify AppSidebar buildSelfNavItems (admins see available channels)
- Add gateway WARN logs for 503 no-available-accounts branches
- Wire ChannelMonitorRunner into provideCleanup for graceful shutdown
- Add migrations 130/131 (CC template userid fix + mimicry field cleanup)
- Clean up fork-only features (sora, claude max simulation, client affinity)
- Remove ~320 obsolete i18n keys
- Add codexUsage utility, WechatServiceButton, BulkEditAccountModal
- Tidy go.sum

When the service restarts, concurrency slots from the old process
remain in Redis, causing phantom occupancy. On startup, scan all
concurrency sorted sets and remove members with non-current process
prefix, then clear orphaned wait queue counters.

Uses Go-side SCAN to discover keys (compatible with Redis client
prefix hooks in tests), then passes them to a Lua script for
atomic member-level cleanup.

系统性地修复、补充和强化项目的自动化测试能力：

1. 测试基础设施修复
   - 修复 stubConcurrencyCache 缺失方法和构造函数参数不匹配
   - 创建 testutil 共享包（stubs.go, fixtures.go, httptest.go）
   - 为所有 Stub 添加编译期接口断言

2. 中间件测试补充
   - 新增 JWT 认证中间件测试（有效/过期/篡改/缺失 Token）
   - 补充 rate_limiter 和 recovery 中间件测试场景

3. 网关核心路径测试
   - 新增账户选择、等待队列、流式响应、并发控制、计费、Claude Code 检测测试
   - 覆盖负载均衡、粘性会话、SSE 转发、槽位管理等关键逻辑

4. 前端测试体系（11个新测试文件，163个测试用例）
   - Pinia stores: auth, app, subscriptions
   - API client: 请求拦截器、响应拦截器、401 刷新
   - Router guards: 认证重定向、管理员权限、简易模式限制
   - Composables: useForm, useTableLoader, useClipboard
   - Components: LoginForm, ApiKeyCreate, Dashboard

5. CI/CD 流水线重构
   - 重构 backend-ci.yml 为统一的 ci.yml
   - 前后端 4 个并行 Job + Postgres/Redis services
   - Race 检测、覆盖率收集与门禁、Docker 构建验证

6. E2E 自动化测试
   - e2e-test.sh 自动化脚本（Docker 启动→健康检查→测试→清理）
   - 用户注册→登录→API Key→网关调用完整链路测试
   - Mock 模式和 API Key 脱敏支持

7. 修复预存问题
   - tlsfingerprint dialer_test.go 缺失 build tag 导致集成测试编译冲突
