fix(ci): resolve docker compose race condition in prod deployment

Stop containers explicitly before pulling + restarting to prevent the
'No such container' race condition where Docker Compose tries to start
a new container while simultaneously removing the old one.

Also remove --no-deps flag which caused stale hash-prefixed container
names (e.g. 41cb964156c0_libnovel-ui-1) that trigger the race.
