feat(docker compose): healthcheck for speckle-server

[iainsproat]

Description & motivation

For speckle deployed via Docker Compose, there are conditions where the speckle server container becomes unresponsive but has not yet exited with a non-zero exit code. For example, this issue report #1649

This Pull Request introduces a health check to the pod which will cause non-responsive pods to be automatically restarted after 30s.

This is a workaround for the symptoms (unresponsiveness of the speckle-server pod), and not a fix for the root cause.
