Add --move mode to sonarr_classification_scan.sh, matching Radarr

Acts on forward misplacements and reverse-kids-leak (adult content in
the kids root — not a judgment call, same reasoning as the Radarr
side), moving to the new SONARR_GENERAL_ROOT config var. Reverse-anime
-leak stays report-only — deliberate style placements like Castlevania
are common and valid there. episodeFileCount is Sonarr's hasFile
equivalent: series with 0 files get relocated + an immediate
SeriesSearch instead of a file move. One series at a time, verified
after each — matches the race condition found doing this by hand for
the Fate/Zero and Fate/Stay Night moves earlier in the session.
