feat(pricing): add GPT-5 Codex model pricing presets

Add pricing configuration for GPT-5 Codex variants to support cost tracking for Codex-specific models. Changes: - Add gpt-5-codex model with standard GPT-5 pricing - Add gpt-5-1-codex model with standard GPT-5.1 pricing - Input: $1.25/M tokens, Output: $10/M tokens - Cache read: $0.125/M tokens, Cache creation: $0 This ensures accurate cost calculation for Codex API requests using GPT-5 Codex models.

-# CC Switch 代理功能使用指南
-
-## 功能介绍
-
-CC Switch 的代理功能是一个本地 HTTP 代理服务器，可以统一管理 Claude Code、Codex 和 Gemini CLI 的 API 请求。主要特性包括：
-
- **统一代理入口** - 所有 CLI 应用的请求通过本地代理转发
- **自动故障转移** - 当前供应商故障时自动切换到备用供应商
- **按应用控制** - 可独立控制每个应用是否启用代理
- **配置保护** - 自动备份原始配置，停止代理时安全恢复
-
-## 快速开始
-
-### 1. 启动代理
-
-在 CC Switch 主界面，点击右上角的 **Proxy** 按钮，可以看到代理控制面板。
-
-点击 **启动代理** 按钮启动本地代理服务器。代理默认监听 `127.0.0.1:15721`。
-
-### 2. 启用应用接管
-
-代理启动后，你可以选择让哪些应用的请求通过代理：
-
- **Claude** - 接管 Claude Code 的 API 请求
- **Codex** - 接管 Codex CLI 的 API 请求
- **Gemini** - 接管 Gemini CLI 的 API 请求
-
-点击对应应用的开关即可启用/禁用接管。
-
-> **注意**：启用接管后，CC Switch 会自动修改对应应用的配置文件，将 API 端点指向本地代理。原始配置会被安全备份。
-
-### 3. 正常使用 CLI
-
-启用接管后，你可以正常使用各个 CLI 工具。所有请求都会经过 CC Switch 代理转发到配置的供应商。
-
-### 4. 停止代理
-
-当你不再需要代理时，点击 **停止代理** 按钮。CC Switch 会：
-
-1. 安全关闭代理服务器
-2. 自动恢复所有应用的原始配置
-3. 清除代理状态
-
-## 自动故障转移
-
-### 工作原理
-
-代理功能内置了智能故障转移机制：
-
-1. **健康监控** - 实时监控每个供应商的响应状态
-2. **熔断器** - 连续失败 5 次后触发熔断，暂停使用该供应商
-3. **自动切换** - 熔断后自动切换到列表中的下一个供应商
-4. **自动恢复** - 30 秒后尝试恢复熔断的供应商
-
-### 配置故障转移
-
-要使用故障转移功能，你需要：
-
-1. 在对应应用下添加多个供应商（至少 2 个）
-2. 启动代理并启用接管
-3. 当主供应商故障时，代理会自动切换到备用供应商
-
-### 健康状态指示
-
-在供应商卡片上可以看到健康状态指示：
-
- **绿色** - 供应商正常
- **红色** - 供应商故障/熔断中
- **灰色** - 未使用代理或未检测
-
-## 按应用接管
-
-v3.9.0 新增了按应用分粒度控制功能：
-
- 你可以只接管 Claude，而让 Codex 使用原始配置
- 每个应用的接管状态独立管理
- 启用/禁用不会影响其他应用
-
-### 接管状态检测
-
-CC Switch 通过检测配置备份来判断接管状态：
-
- 存在备份 = 已接管
- 无备份 = 未接管
-
-这确保了即使 CC Switch 异常退出，重新启动后也能正确识别状态。
-
-## 代理配置
-
-在代理面板中，你可以配置以下参数：
-
-| 参数 | 默认值 | 说明 |
-|------|--------|------|
-| 监听地址 | 127.0.0.1 | 代理服务器绑定地址 |
-| 监听端口 | 15721 | 代理服务器端口 |
-| 最大重试 | 3 | 请求失败时的最大重试次数 |
-| 请求超时 | 120 秒 | 单个请求的超时时间 |
-| 启用日志 | 是 | 是否记录请求日志 |
-
-## 常见问题
-
-### Q: 代理启动失败，提示端口被占用？
-
-A: 默认端口 15721 可能被其他程序占用。你可以：
- 关闭占用该端口的程序
- 在代理配置中修改端口号
-
-### Q: 启用接管后 CLI 无法使用？
-
-A: 请检查：
-1. 代理服务器是否正常运行（查看代理面板状态）
-2. 供应商配置是否正确（API Key 等）
-3. 网络连接是否正常
-
-### Q: 如何恢复原始配置？
-
-A: 点击 **停止代理** 按钮，CC Switch 会自动恢复所有应用的原始配置。
-
-如果 CC Switch 异常退出，重新启动后会检测到之前的备份，你可以：
- 点击停止代理来恢复配置
- 或继续使用代理功能
-
-### Q: 故障转移没有生效？
-
-A: 请确保：
-1. 配置了至少 2 个供应商
-2. 代理已启动且接管已启用
-3. 故障转移只在代理模式下工作
-
-### Q: 代理会影响性能吗？
-
-A: 本地代理的延迟开销非常小（通常 < 1ms）。但如果启用了请求日志，在高频请求场景下可能会有少量性能影响。
-
-## 技术细节
-
-### 配置文件位置
-
-启用接管后，CC Switch 会修改以下配置文件：
-
-| 应用 | 配置文件 | 修改内容 |
-|------|----------|----------|
-| Claude | `~/.claude/settings.json` | `apiBaseUrl` 指向代理 |
-| Codex | `~/.codex/config.toml` | `[api] baseUrl` 指向代理 |
-| Gemini | `~/.gemini/.env` | `GEMINI_BASE_URL` 指向代理 |
-
-原始配置备份在 CC Switch 数据库中，停止代理时自动恢复。
-
-### 代理模式
-
-代理服务器运行在接管模式下，会：
-
-1. 接收来自 CLI 的 HTTPS 请求
-2. 根据当前供应商配置转发到真实 API 端点
-3. 返回响应给 CLI
-4. 记录请求日志和健康状态
-
-### 数据库表
-
-代理功能使用以下数据库表：
-
- `proxy_config` - 代理配置
- `provider_health` - 供应商健康状态
- `proxy_request_logs` - 请求日志
- `circuit_breaker_config` - 熔断器配置
- `proxy_live_backup` - Live 配置备份

YoVinchen	af9785f566	fix(ui): restore card borders in usage statistics panels Restore proper card styling for ModelTestConfigPanel and PricingConfigPanel by adding back border and rounded-lg classes. The transparent background styling was causing visual inconsistency. Changes: - Replace border-none bg-transparent shadow-none with border rounded-lg - Apply to both loading and error states for consistency - Format TypeScript code for better readability - Break long function signatures across multiple lines This ensures the usage statistics panels have consistent visual appearance with proper borders and rounded corners.	2025-12-04 11:33:33 +08:00
