Stop dropping seasons Plex reports without a parentRatingKey

Browse source 
The first real scan logged 15 "episode has no season; skipped" warnings. They
are Firefly S1 in TV Show Archive: Plex returns those episodes with
grandparentRatingKey and parentIndex set and parentGuid present, but
parentRatingKey null. Requiring parentRatingKey meant the entire season was
silently absent from the report - exactly the kind of quiet omission a reclaim
tool must not have.

The season key is now synthesized from show + season number when Plex omits it,
which is stable across scans. Keep marks are unaffected either way since they
key on GUIDs, not rating keys.

Also drops the multi_part flag from ordinary seasons. A season has one part per
episode, so part_count > 1 is normal there and the badge appeared on every TV
row; it now means what it says - a movie held more than once, or a season with
more files than episodes.

Both cases are in the fake server now, so the suite covers them.
