Remove hardcoded defaults for preview variant and width in database schemas to allow more flexible preview generation. Bump preview cache schema version and add versioning to cache rows for consistency. Switch preview image generation to 480px JPEGs with updated file naming and content type. Refactor PDF preview rendering to support configurable output format and quality, and update all preview consumers to use unified "image" buffer property instead of "png". Add migration scripts and update metadata for both Postgres and SQLite. BREAKING CHANGE: Preview variant and width defaults removed from database; preview cache and image handling updated across system.
