Header/code audit fixes across all core scripts

Behavior fixes:
- docker_daily_restart.sh: implement RESTART_VERIFY_WAIT sleep before
  verify_running() — variable was logged as config but never applied
- cert_monitor.sh: --log now shows expiry date and days remaining for
  healthy domains in the per-domain summary; problems always show details

Header corrections:
- downloaders_reset.sh: fix frequency contradiction (15 min → 30 min)
- lidarr_cleanup.sh: Emby scan triggers on actual deletions, not every run
- ssh_setup.sh: document --local-only flag in USAGE section
- zfs_memory_snapshot.sh: clarify dry-run skips log write in PURPOSE
- ramdisk_stop.sh / ramdisk_setup.sh: document TRANSCODE_STATE_FILE var
- smart_long_test.sh: remove SMART_TEMP_WARN/CRIT — not used in code
