Add verbose log() coverage across all watchdog scripts

docker_watchdog: config dump at startup (thresholds/limits), skip list shown when active, per-container healthy log for Tier1 required + mem/CPU monitored containers
stability_watchdog: config dump with all tier thresholds, log() on pass for rootfs/log/tmp/load/zombies/NIC checks (previously silent on clean)
resource_watchdog: config dump with all pressure thresholds and container lists, log normal pressure state with live RAM/load values
system_watchdog: per-script timing on each child script run
network_watchdog: config dump (internet URL, DDNS domain/container, NPM URL, strike limit)
storage_watchdog: config dump (growth threshold, log max, paths, suppress ceilings)
webgui_watchdog: log nginx worker and php-fpm worker counts on healthy check
