fix(prune): add --filter until=1h to network prune

docker network prune -f removes ALL unused networks, including ones
that molecule tests are actively creating (e.g. 'traefik' network
created during molecule create phase before containers are attached).
This caused "network traefik not found" errors in CI molecule tests.

Add --filter "until=1h" to only prune networks older than 1 hour,
matching the container prune filter.
