Merge pull request 'Allow serienen/videoen categories in movetdarr' (#5) from fix/movetdarr-en-categories-20260916 into main

Die Kategorie-Whitelist kannte nur serien4k|serien|video4k|video. Die
englischen Arr-Instanzen sonarrEN (Port 8991, Root /data/FHD/serienen) und
radarrEN (Port 7880, Root /data/FHD/videoen) nutzen aber serienen/videoen.

Folge: Downloads dieser Kategorien wurden mit "nicht unterstuetzte Kategorie"
abgewiesen und blieben in /usenet/complete liegen, ohne je in den
FileFlows/Arr-Flow zu gelangen. Gefunden: Mutiny.2026 x2 (08./09.09.2026,
zusammen ~21 GB), beide Filme in radarrEN weiter monitored/hasFile=false.

/tdarr/complete/{serienen,videoen} existieren bereits; die FileFlows-Library
scannt /tdarr/complete rekursiv, es braucht also nur die Whitelist.

2 neue Testfaelle (serienen + videoen), test_movetdarr.py und
test_movetdarr_parallel.py gruen.
