Media echo/log audit pass — 11 scripts + Manual

Remove setup banners from all 8 scripts that had them (discovery scripts
use comment-only setup sections). Move per-item/detail echoes to log in
arr_sync, lidarr_missing_art, lidarr/radarr/sonarr_cleanup (scan progress,
API query status, root/orphan config lines), and per-title lines in
radarr_tmdb_removed / sonarr_tvdb_removed. Fix log→echo on clean-status
summary lines in arrs_failed_stalled_recovery, media_cleaner, and both
removed-title scripts. Add output tiers section to Manual-Media.md.
