Add movies/series filmography to company detail

GET /companies/{id} showed only the company's own info. Adds movies
and series lists (any role: production, distribution, network),
ordered by release/first-air date, read straight off the existing
movie_companies/series_companies junction rows -- no separate sync
needed since those only ever exist as a side effect of ingesting the
movie or series itself.
