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

- 接入 gpt-5.4 模型识别与规范化，补充默认模型列表
- 增加 gpt-5.4 输入/缓存命中/输出价格与计费兜底逻辑
- 同步前端模型白名单与 OpenCode 上下文窗口（1050000/128000）

(cherry picked from commit 924476dcac6181cd0f3ee731ec7b73672ff03793)

Replace `<` comparisons with Math.max/ternary+>= to avoid Vue template
parser treating `<` as HTML tag start in attribute values.

- Fix bulk edit: send 0 instead of null/NaN to clear load_factor
- Fix edit modal: explicit NaN check instead of implicit falsy
- Fix create modal: use ?? instead of || for load_factor
- Add load_factor upper limit validation (max 10000)
- Add //go:build unit tag and self-contained intPtrHelper in test
- Add design intent comments on WaitPlan.MaxConcurrency

新增 UMQ (User Message Queue) 双模式支持:
- serialize: 账号级分布式串行锁 + RPM 自适应延迟（严格限流）
- throttle: 仅 RPM 自适应前置延迟，不阻塞并发（软性限速）

后端:
- config: 新增 Mode 字段，保留 Enabled 向后兼容
- service: 新增 UserMessageQueueService（Lua 锁/延迟算法/清理 worker）
- repository: 新增 UserMsgQueueCache（Redis Lua acquire/release/force-release）
- handler: 新增 UserMsgQueueHelper（SSE ping + 等待循环 + throttle）
- gateway: 按 mode 分支集成 serialize/throttle 逻辑
- lint: 修复 gofmt rewrite rules、errcheck 类型断言、staticcheck QF1012

前端:
- 三态选择器 UI（关闭/软性限速/串行队列）替代 toggle 开关
- BulkEdit 支持 null 语义（不修改）
- i18n 中英文文案

通过 6 轮专家评审（42 次 review）、golangci-lint、单元测试、集成测试。

- BulkUpdate handler: add structured details to 409 response
- BulkUpdateAccounts: simplify to global pre-check before any DB write;
  remove per-account snapshot tracking which is no longer needed
- MixedChannelError.Error(): restore English message for API compatibility
- BulkEditAccountModal: use t() with details for both pre-check and 409
  fallback paths instead of displaying raw backend strings
- Update test to verify pre-check blocks on existing group conflicts

Previously, preCheckMixedChannelRisk() skipped when selectedPlatforms
had more than one entry, and the catch block in submitBulkUpdate had no
409 handling — so multi-platform conflicts just showed a generic error.

- Rename canPreCheck(): only call pre-check API for single-platform
  antigravity/anthropic selections (API requires a single platform param)
- Pass `built` into preCheckMixedChannelRisk() so pendingUpdatesForConfirm
  is set before returning false
- submitBulkUpdate: add 409 mixed_channel_warning catch as fallback for
  multi-platform case, saving baseUpdates for retry
- Remove needsMixedChannelCheck() gate on confirm_mixed_channel_risk flag;
  use mixedChannelConfirmed alone so multi-platform retry also works

The response interceptor in client.ts transforms errors into plain
objects {status, code, message}, but catch blocks were checking
error.response?.status (AxiosError format) which never matched.

- Add error field passthrough in client.ts interceptor
- Refactor BulkEditAccountModal to use pre-check API (checkMixedChannelRisk)
  before submit, matching the single edit flow
- Fix EditAccountModal catch blocks to use interceptor error format
- Add bulk-update mixed channel unit tests

- Move mixed channel check before any DB writes in BulkUpdateAccounts
- Return 409 from BulkUpdate handler for MixedChannelError
- Add ConfirmDialog to BulkEditAccountModal for mixed channel warning
- Update mixed channel warning message to Chinese

- Move IncrementRPM after Forward success to prevent phantom RPM
  consumption during account switch retries
- Add base_rpm input sanitization (clamp to 0-10000) in Create/Update
- Add WindowCost scheduling checks to legacy path sticky sessions
  (4 check sites + 4 prefetch sites), fixing pre-existing gap
- Clean up rpm_strategy/rpm_sticky_buffer when disabling RPM in
  BulkEditModal (JSONB merge cannot delete keys, use empty values)
- Add json.Number test cases to TestGetBaseRPM/TestGetRPMStickyBuffer
- Document TOCTOU race as accepted soft-limit design trade-off

Without this, submitting a bulk edit with only RPM changes would be
rejected as "no fields selected".

- Use TxPipeline (MULTI/EXEC) instead of Pipeline for atomic INCR+EXPIRE
- Filter negative values in GetBaseRPM(), update test expectation
- Add RPM batch query (GetRPMBatch) to account List API
- Add warn logs for RPM increment failures in gateway handler
- Reset enableRpmLimit on BulkEditAccountModal close
- Use union type 'tiered' | 'sticky_exempt' for rpmStrategy refs
- Add design decision comments for rdb.Time() RTT trade-off

- useModelWhitelist.ts 添加 gpt-5.3-codex、gpt-5.3-codex-spark
- BulkEditAccountModal.vue 添加 5.3 模型选项与预设按钮（含 5.2→5.3 升级映射）

- 新增 selectedPlatforms prop，从父组件传入选中账号的平台集合
- 根据选中平台过滤模型列表与预设映射按钮，避免误操作
- 混选多平台时显示 amber 警告横幅，提醒用户注意映射适用性
- 仅警告不阻断，保持加法兼容

Add Gemini model presets to BulkEditAccountModal for bulk model mapping.
Fix AccountStatusIndicator model rate limit grid layout using proper
grid container.

- Force cache billing support
- Model identity injection in prompts with leak prevention
- Thinking mode auto-handling (max_tokens/budget_tokens fix)
- Frontend: whitelist mode toggle, model mapping validation, status indicators
- Gemini session fallback with Redis Trie O(L) matching
- Ops: enhanced concurrency monitoring, account availability, retry logic
- Migration scripts: 049-051 for model mapping unification

- 普通用户 Group DTO 移除 model_routing/account_count/account_groups，避免泄露内部路由与账号信息\n- 新增 AdminGroup DTO，并仅在管理员分组接口返回完整字段\n- 前端拆分 Group/AdminGroup，管理端页面与 API 使用 AdminGroup\n- 增加 /api/v1/groups/available 契约测试，防止回归

- 新增 accounts.rate_multiplier（默认 1.0，允许 0）
- 使用 usage_logs.account_rate_multiplier 记录倍率快照，避免历史回算
- 统计/导出/管理端展示账号口径费用（total_cost * account_rate_multiplier）

- 修改 HandleUpstreamError 逻辑，启用自定义错误码时所有在列表中的错误码都会停止调度
- 添加 handleCustomErrorCode 函数处理自定义错误码的账号停用
- 前端添加 429/529 错误码的警告提示，因为这些错误码已有内置处理机制
- 更新 EditAccountModal、CreateAccountModal、BulkEditAccountModal 的错误码添加逻辑
