perf(calendar): move day-grouping server-side via group=day

Drops the client-side `coalesceEpisodes` from the calendar feeds and asks the
worker to collapse same-show-same-day episodes with `?group=day`. The shows,
media and hot-releases queries now pass `group=day`; their mappers render the
server's grouped cards directly (`mapToUpcomingEpisodeEntry` carries the nested
`episodes` for `multiple_episodes` cards). Bumps @trakt/api to 0.4.25.

`coalesceEpisodes` stays (still used by `coalesceBinges`). `mapToPostCredits`
takes a structural param so it accepts the widened calendar episode.
