fix(rego-tunnel): Make app work out of the box from repo

- Add init-rego.sh and xstartup to repo's shared folder
- Update docker-compose.json with all volume mounts
- Update docker-compose.yml with cgroup: host
- Mount scripts directly from repo (not user-config)

Now works on fresh install without any user-config overrides.
