perf(calendar): serve hot releases from a single endpoint

Replaces the client-side hot releases assembly (a releases-calendar fetch
plus separate trending and anticipated fetches per media type, then an
in-browser intersect) with one request to the new
`/calendars/releases/hot` endpoint, which does the gating and merge
server-side and returns the feed already ordered by availability date.

The mapper now just discriminates the union response, coalesces episodes and
sorts. Drops the now-dead `sourceLimit` param from both callers and the
`HideRecommended` invalidations. Bumps @trakt/api to 0.4.22 for the new
contract.
