feat(kobo): add manual KOReader book hash linking and unmatched tracking

When KOReader syncs progress or annotations, it identifies books by a document
hash. BookOrbit normally resolves this automatically, but some books cannot be
matched. This adds a tracking table for unmatched hashes and a UI to manually
link them to existing library books.

Closes #458
