fix stale doc references across four files

README.md:
  - folder tree: conf files at root → Configurations/ subfolder
  - folder tree: Failover/ → Fallback/, wrong README name corrected
  - folder tree: add Kernel/ entry (was missing)
  - CONFIGURATION section: note Configurations/ path + sparse checkout

README-User_Script_Plug-in.md:
  - mem_shutdown_active attributed to stability_watchdog → resource_watchdog

unRAID_Essentials/README-Unraid_Essentials.md:
  - webgui_watchdog schedule: "Every 10 min via User Scripts" →
    "Every minute via watchdog_orchestrator → system_watchdog"
  - HOW THE SCRIPTS RELATE: arrow diagram corrected — system_watchdog.sh
    calls storage/webgui/network watchdogs, not the reverse; added
    network_watchdog.sh and stability_watchdog.sh to the flow

Orchestrators/README-Orchestrators.md:
  - continuous daemon example: system_watchdog.sh → fallback.sh
    (system_watchdog is now single-pass, not a daemon)
  - scripts table: add watchdog_orchestrator.sh and monthly_maintenance.sh
    (both were missing)
