Marcel 09fc871756 feat(backend): add ThumbnailBackfillService for regenerating missing thumbnails ...

Sequentially processes all documents with a file but no thumbnail and
tallies processed / skipped / failed counts. Runs on thumbnailExecutor
so it shares back-pressure with live upload thumbnails but can never
saturate them (single-threaded loop).

Concurrent start rejected with THUMBNAIL_BACKFILL_ALREADY_RUNNING.
Emits a structured summary log line on completion for operator
visibility.
