feat(docker compose): healthcheck for speckle-server (#1651)

* feat(docker compose): healthcheck for speckle-server
- if speckle server pod becomes unresponsive (but has not yet exited with a non-zero exit code), it will be automatically restarted after 30s.

* feat(1click): add healthcheck to speckle-server container running in DigitalOcean 1click

* fix(1click): remove command statements
- the docker image is responsible for providing these

docker-compose-speckle.yml
