fix: support host storage paths and clean up cancelled deployments

Allow validated host file and directory mounts outside resource directories
while protecting external paths from deletion.

Clean up cancelled deployment containers and clear tracked process IDs.
Preserve legacy KeyDB and Dragonfly password parsing, accept server backup
paths without extension restrictions, and allow Compose variable proxy ports.
