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.

+## Output Tiers
+
+All tools have two output levels controlled by `--log`.
+
+Without `--log`, each script processes and always concludes with a summary block
+showing identity, duration, counts, and a status line. Warnings and errors are
+always visible. State-display scripts (watchdog_skip_list_manager, zfs_pool_scrub
+`--status`, fallback_state_reset current-state section) always show their state
+output — `--log` adds configuration detail and per-item resolution within each
+section.
+
+With `--log`, per-item detail appears: individual items added/skipped, per-database
+check results, per-pool scan lines, per-container stop/start state, per-directory
+creation results. Use when debugging unexpected results or confirming a first run.
