Home grid no longer shows wrong covers after a library wipe + re-ingest
If you ever wiped your CWA library and re-ingested a different set of books, the home grid would show covers from your previous library bound to the new books — clicking into a book would show the correct cover, but the thumbnail grid was a mess. The fix lets the server detect that a thumbnail predates the book it claims to represent, falls back to serving the on-disk cover for the current request, and quietly regenerates the thumbnail so the next page load is also correct.
You don't need to click anything — browsing the affected pages now self-heals the cache as you go.
