Saving failed with 400 'Unknown domain.' because queue items carry the
legacy domain 'core', which the old bot mapped to 'uc' for a2loft URLs —
my domain validation (added in the review pass) rejected it. The save now
applies the same alias before validating and forwarding.
Also: the client showed axios's generic 'Request failed with status code
400' because the catch destructured error.message; all cropper handlers now
prefer the server's response.data.message (errMessage helper), so the real
reason is visible.
Verified: save with a 'core' item forwards to /identity/uc/profile/picture;
a 400 shows 'Unknown domain.'; 46 tests.
