- Add /api/v1/ prefix to all Unit 2 API calls (Setup/status, Setup/owner,
Invitation/validate, Invitation/complete) to match backend ApiPrefixConvention
- Fix setup status endpoint to POST /api/v1/Setup/owner (not /Setup)
- Handle PascalCase 'Initialized' response from .NET backend without camelCase policy
- Update all MSW mock handlers to match corrected /api/v1/ URL patterns
- Remove unused imports from RouteGuard.test.tsx
Root cause: backend uses ApiPrefixConvention('api/v1') but frontend calls
were missing the prefix, and .NET defaults to PascalCase JSON serialization.
