fix(media): a series is the name before the episode marker

Keyed on the whole episode title, every episode of a box set became a group of
one and never reached the five-episode size that calls something a series, so
the live run filed 124 Monk episodes as 124 movie folders, each named after its
own episode. ep_of now returns the series — the name before SxxEyy / 1x04 /
Part N — and the planner groups and names the quarantine pile by that series,
so one show is one pile: 'Monk - S05E03 - Mr. Monk and the Big Game' is series
monk. The threshold keeps its job: a lone film named Part 2 stays a film.

Re-planning the live census with this moves nothing differently except the 124
Monk files, which now join the TV pile: 168 episode files across 3 series.
