fix: resolve 4 TypeScript compilation errors from CI

- AuditLogPage: e.details -> e.detail (correct property name)
- AgentInstance: BarChart x: number -> x: String(i) (BarSeries requires string)
- AppsTab: add missing CatalogRoute import
- Dashboard: wrap MonoText in span for title attribute (MonoText lacks title prop)
