Docker Compose gives a recreated container the old mount at each path
that the image declares with VOLUME, also a volume deleted in Coolify.
Before `up`, remove only containers that still mount a Coolify volume
whose storage entry was deleted. The stale volume delete dialog now
warns when a container still uses the volume.
Closes#6875
