## Summary
- Resolve standard field `label`, `description`, and `icon` overrides
through dedicated GraphQL field resolvers.
- Fall back to the source locale safely when the request locale is
missing, and allow direct overrides to apply for non-source locales when
translations are absent.
- Enrich metadata subscription payloads for both `before` and `after`,
reusing the same override application path for field and object
metadata.
- Update and extend tests to cover the revised override behavior.
## Testing
- Updated unit coverage for standard override resolution, including the
non-source-locale fallback path.
- Not run (not requested).
