behavior change: save_post_file's category_fetcher argument is now
keyword-only with no default, so every call site has to pass something
explicit (fetcher instance or None). Previously the =None default let
bookmark→library save and bookmark Save As slip through without a
fetcher at all, silently rendering %artist%/%character% tokens as
empty strings and producing filenames like '_12345.jpg' instead of
'greatartist_12345.jpg'.
BookmarksView now takes a category_fetcher_factory callable in its
constructor (wired to BooruApp._get_category_fetcher), called at save
time so it picks up the fetcher for whatever site is currently active.
tests/core/test_library_save.py pins the signature shape and the
three relevant paths: fetcher populates empty categories, None
accepted when categories are pre-populated (Danbooru/e621 inline),
fetcher skipped when template has no category tokens.
