Adds Komga sync feature to import read status from a Komga server.
Books are matched by title (case-insensitive) with series+title primary
match and title-only fallback. Sync reports are persisted with matched,
newly marked, and unmatched book lists. UI shows check icon for newly
marked books, sorted to top. Credentials (URL+username) are saved
between sessions. Uses HashSet for O(1) lookups to handle large libraries.
