fix: handle canonicalized route responses

[aofei]

Handle moved-resource responses from the backend without generic write retries, and retry updateProject once with the canonical route so saving existing projects still works after a project rename.

Replace unresolved user, project, and editor routes with canonical backend values after loading so subsequent UI behavior uses canonical identifiers consistently.

Updates #2993

[xgopilot]

Clean, well-structured fix. The canonical retry logic in updateProject, the useResolvedUser composable, and the project-route.ts utility are all good separations of concern. New unit tests for both Client and updateProject add confidence around the moved-resource edge cases.

Pull request overview

This PR adds frontend support for backend route canonicalization by (1) surfacing moved-resource conflicts with canonical identifiers and (2) updating UI routes/queries to use canonical user/project identifiers after loading, so subsequent behavior is consistent (e.g., saving after rename).

Changes:

• Add a 40901 errorResourceMoved API exception path with canonical route metadata support in the API client.
• Retry updateProject once using the canonical {owner,name} from moved-resource metadata.
• Canonicalize community user/project routes after resolving from backend, and propagate canonical identifiers into subsequent queries/operations.
