docker_update: prune dangling images after pull (both normal and remainder modes)

Browse Source 
Daily restarts create orphaned images that were never cleaned up.
Added docker image prune -f section matching docker_update_remaining.sh pattern.
Prune runs each cycle so orphans from the previous day's restart are removed daily
rather than waiting for the weekly docker_update_remaining.sh sweep.
