GET /movies and GET /series accept a genre filter (an Aurora genre id),
but nothing exposed what those ids actually are -- genres otherwise
only ever appear embedded in a movie/series response's own genres
list. This is the resolve-by-name-first-then-filter step the frontend
needs to build real genre browsing.
No filter, no sort_by -- always alphabetical by name, same pattern as
collections/companies (genres have no categorical field or popularity/
date to sort by). page_size defaults to 50 (max 200) rather than the
20/50 used elsewhere, since genres are a small, fixed reference set
(TMDb has ~19-20 total) a client typically wants in full for a filter
dropdown, not paginated like a catalog of millions of movies.
Also fixed two stale "behind Traefik" mentions in app/main.py's module
docstring while touching this file, left over from the earlier
cPanel/host-webserver deployment change.
