Tools echo/log audit pass — 9 scripts + Manual

No setup banners to remove (Tools folder was already clean). Fix log→echo
on summary status/conclusion lines across container_data_export, emby_database_repair,
recreate_shares, zfs_pool_scrub, and fallback_state_reset (safety check + two summary
detail lines). Fix log→echo on status display lines in watchdog_skip_list_manager
(skip list empty, restart history lines). Move per-item "to add" preview echoes to
log in emby_to_lidarr/radarr/sonarr_sync; fix nothing-to-do log→echo in all three.
Add output tiers section to Manual-Tools.md.
