fix(ui): 空catch块添加日志 + ErrorBoundary覆盖高风险组件

空catch块修复 (12处, 6文件):
- ModelsAPI: 4处 localStorage 配置读写添加 console.warn
- VikingPanel: 2处 viking 操作添加日志
- Workspace/MCPServices/SaaSStatus/TOTPSettings: 各1-3处

ErrorBoundary新增覆盖:
- ChatArea: 两种UI模式均包裹(防白屏)
- RightPanel: 两种UI模式均包裹
- AuditLogsPanel/HeartbeatConfig/VikingPanel: 设置页包裹
