Centralize media publication Move media item construction, validation and processing coordination, and metadata insertion into media.Service. HTTP handlers now parse requests, map publication errors, and redirect; uploads.Processor accepts source paths and writes the required variants. The service preserves the files-before-metadata ordering, so a gallery item never points at files that were not written. Its focused tests can assert that orchestration without coupling to HTTP or the filesystem. This is intentionally a publication-only stepping stone. It does not delete files or add recovery behavior, so upload processing retains a write-only storage dependency. Future work can extend the service with recoverable file deletion and soft-delete recovery without adding DeleteFile to upload-facing interfaces again.
