Centralize image sizes and filename logic in MediaItem - Add ResizedWidths() type-awareness (video returns [250,150], photos [850,250,150]) - Add ThumbnailWidths() and ResizedFilename() to MediaItem as single source of truth - Update handlers and import tool to use these methods instead of hardcoded values - Add NOT EMPTY checks to SQL columns that must not be blank strings Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
