fix: respect quoting in procfile commands

Procfile commands for the `docker-local` scheduler were split differently on deploy and on `dokku run`. Deploys failed on escaped quotes, and `dokku run` ignored quotes entirely. Both now split commands using shell quoting rules, and commands containing bare shell operators fail with a clear error, matching the `k3s` scheduler.
