feat: Identity JSON sync + schema-aware column selection

- storage.rs: add local_profile field, check disk for profile.jpg
- tmdb_api.rs: trigger JSON sync after TMDb probe
- identity_api.rs: upload_profile_image triggers JSON sync
- identity_binding.rs: bind/unbind/merge trigger JSON sync
- get_identity_json: Lazy Sync (generates JSON from DB if missing)
- identities.rs + identity_api.rs: use schema-aware column selection (dev:name vs public:real_name)
- Fixes 500 errors on identities endpoints across schemas
