- Fix race condition: guard useEffect when workspaceId is null, prevent
infinite loading state by setting isLoading=false on null workspace
- Fix TypeScript strict typing: @Workspace() returns string|undefined,
controller now matches with BadRequestException guard
- Narrow details DTO type from unknown to Record<string, unknown>|null
- Add error state UI for API fetch failures
- Add error-path test with static mock import pattern
