fix: update checker shows correct status + version display + dark mode fixes

- Fix 'Up to date' shown incorrectly when Codex version changed (add version_changed field)
- Change update status text from <span> to clickable <button>
- Add proxy version number next to 'Server Online' badge
- Fix dark mode for ProxyPool form inputs and AccountCard proxy selector
- Add fingerprintUpdating translation key (zh/en)

+- **四种分配模式** — Global Default（全局代理）、Direct（直连）、Auto（Round-Robin 轮转）、指定代理
+- **健康检查** — 定时（默认 5 分钟）+ 手动，通过 ipify API 获取出口 IP 和延迟
+- **不可达自动标记** — 代理不可达时自动标记为 unreachable，不参与自动轮转
+- **Dashboard 管理面板** — 添加/删除/检查/启用/禁用代理，每个账号可选择代理或模式
