feat: parse and display all available EPUB metadata fields

Browse Source 
Add parsing for dc:publisher, dc:date, dc:subject, dc:rights,
dc:contributor, dc:identifier (prefers ISBN scheme), and
calibre:rating. All new fields serialized in BookMetadataCache
(version bumped to 7) and displayed in BookInfoActivity with
rating shown as N/5 scale.

Made-with: Cursor
