types: Expand ReaderMetadata interface to match server API schema

- Add comprehensive metadata fields from server response (30+ properties)
- Include core identification fields (id, media_item_id, library_id)
- Add content metadata (description, ISBN, series, tags, publisher, etc.)
- Add format identification (format_group, mime_type, file_path, file_size)
- Add library classification (library_type_name, library_type)
- Add comic/manga specific fields (manga_type, reading_direction, series_count)
- Add additional metadata (age_rating, community_rating, story_arc, etc.)
- Add timestamps (created_at, updated_at)
- Maintain backward compatibility with existing properties

This aligns the TypeScript interface with the actual server API response
structure, preventing type mismatches and improving type safety across
the reader codebase.
