fix(preview): gracefully handle deleted preview files - image fallback, cache cleanup, quieter logs

Browse Source 
- Add onerror handler on <img> previews to fallback to no-preview.png
- Fire async cache cleanup when preview file returns 404
- Add ModelCache.clear_preview_by_path() for safe stale-url removal
- Downgrade /api/lm/previews 404 log from warning to debug
