Fix: Docker s6 service configuration for s6-overlay v3

- Migrated from s6-overlay v2 to v3 structure
- Fixed shebang path from /usr/bin/with-contenv to /command/with-contenv
- Removed s6-setuidgid since base image runs as root
- Moved service definition to /etc/s6-overlay/s6-rc.d/
- Container now starts successfully and web interface is accessible
