test(auth): cover refresh route operation id forwarding

Add AuthRoutesTest to lock in the contract for /v1/auth/refresh:
- forwards a valid refreshOperationId UUID into SessionService.refresh
- returns 400 with invalid_request when the operation id is malformed

These tests back the idempotent session refresh behaviour introduced in
4c9e5fe ('Make session refresh retries idempotent').
