feat: orchestrator housekeeping — watchdog array, script mapping, orch reorder

- master.conf: add WATCHDOG_ORCHESTRATOR_SCRIPTS array; watchdog config moved
  from standalone section into orch block alongside all other tiers
- watchdog_orchestrator.sh: iterate WATCHDOG_ORCHESTRATOR_SCRIPTS instead of
  hardcoded paths; display name derived from filename; status block updated
- master.conf orch section reordered: Array Stop → Array Start → Watchdog (1min)
  → Critical (15min) → Intermediate (4hr) → Daily (1am) → Weekly (Sunday)
- arrs_failed_stalled_recovery.sh added to INTERMEDIATE_MAINTENANCE_SCRIPTS
- lidarr_missing_art.sh moved from intermediate to daily
- clear_logs.sh added to WEEKLY_MAINTENANCE_SCRIPTS (was documented but orphaned)
- playback_aware_lidarr_discovery.sh placed in weekly (commented out, WIP)
- master_host1.conf: Slskd added to DAILY_RESTART_CONTAINERS
