Add genre and content rating storage and display on title pages

Store TMDB genres in normalized tables (genres + titleGenres) and content
ratings as a column on titles. Both are fetched during import/refresh using
append_to_response for content ratings (no extra API calls). Displayed in
the title hero between type badge and year. Also fixes pre-existing type
error for profile_path on TmdbSearchResult.
