Add anime/kids content misclassification detection for Radarr and Sonarr

Overseerr lets users request content into the wrong root folder; these
new report-only scans classify every tracked movie/series (anime, kids,
regular) from metadata alone and flag mismatches against the actual
root folder, in both directions. Rules were validated against real
library data before being adopted — see the header comments in each
script and the master.conf notes above the curated lists.

+# general umbrella studios (Walt Disney Pictures, Paramount Pictures), general streaming
+# platforms (Netflix, Disney+, Hulu), and networks that carry mixed content under one name
+# (The WB, UPN) are deliberately excluded even though they produce plenty of kids/anime
+# content — they also produce just as much non-kids/non-anime content under the same name.

+# Anime always takes priority over kids when both signals could apply (explicit user rule).
