[bug] KOReader Sync: book read status not updated when progress reaches 100%

[crocodilestick]

Summary

When KOReader sync pushes 100% reading progress for a book, CWA correctly receives and stores the progress value but does not mark the book as "Read" / "Finished" in the library. The KOReader Progress field shows 100% but the read-status checkbox remains unchecked.

Steps to reproduce

1. Download a book on a KOReader device via OPDS
2. Read to the end (100% progress, finished status in KOReader)
3. Sync progress via the CWA KOReader Sync plugin
4. Check the book in CWA — progress shows 100% but "Read" checkbox is not ticked

Expected behavior

When a book reaches 100% reading progress via KOReader Sync, the book should be automatically marked as Read in CWA.
