fix(nfo): pass anime_service to _create_or_update_nfo in anime endpoints

POST /api/anime/{key}/regenerate-nfo and PUT /api/anime/{key}/settings
(both of which can regenerate NFO when apply_to_nfo=True) were calling
_create_or_update_nfo without the required anime_service argument,
producing HTTP 500 with 'missing 1 required positional argument:
anime_service' on the anime-settings page.

Also drops the unused series_data parameter from
_create_or_update_nfo's signature — the value was constructed at every
call site but never read inside the function body. All four callers
in anime.py and nfo.py are updated to match.
