The Library tab's single-delete and multi-delete context menu
actions called .unlink() directly, bypassing delete_from_library
entirely. They only extracted post_id from digit-stem filenames
(int(stem) if stem.isdigit()), so templated files like
artist_12345.jpg got deleted from disk but left orphan
library_meta rows that made get_saved_post_ids lie forever.
Fix: resolve post_id via db.get_library_post_id_by_filename first
(handles templated filenames), fall back to int(stem) for legacy
digit-stem files, then call db.remove_library_meta(post_id) after
unlinking. Both single-delete and multi-delete paths are fixed.
This was the last source of orphan library_meta rows. With this
fix + the earlier delete_from_library cleanup, every deletion
path in the app now cleans up its meta row:
- Library tab single delete (this commit)
- Library tab multi delete (this commit)
- Browse/preview "Unsave from Library" (via delete_from_library)
- Browse multi-select "Unsave All" (via delete_from_library)
- Bookmarks "Unsave from Library" (via delete_from_library)
