Add series endpoint parity: /credits, /images, /videos

Movies have separate /credits, /images, /videos sub-endpoints; series
only had /seasons. Adds the matching three for series, reusing the
same cast/crew/creators three-way split series detail already does
(extracted into _split_series_credits so both share it).
