修复: 设置页渲染崩溃(AdvancedSection clampApprovalTimeout 打包后 TDZ)

- 根因:VALID_APPROVAL_TIMEOUTS 常量定义在文件末尾,但 clampApprovalTimeout 在 settings reactive 初始化时调用。Rollup 打包后 const 声明顺序变了,导致 TDZ
- 修复:把 VALID_APPROVAL_TIMEOUTS + clampApprovalTimeout 移到 settings reactive 之前
- 附带修复:@/i18n 去掉对 @/stores/appSettings 的 import,改直读 localStorage,消除循环依赖链
