The tag search filter in refresh() used f.stem.isdigit() to
extract post_id — templated filenames like artist_12345.jpg
failed the check and got filtered out even when their post_id
matched the search query.
Fix: look up post_id via db.get_library_post_id_by_filename
first (handles templated filenames), fall back to int(stem) for
legacy digit-stem files. Same pattern as the delete and saved-dot
fixes from earlier in this refactor.
