Previously, we used 307 Internal Redirect to tell k8s that we're still
waiting for the healthcheck window to fill up. Unfortunately, k8s
assumes 3XX as a success, which wrongly tells it that the service is
ready. Changing to 503 causes the expected probe failure to appear
when the healthcheck state is not yet determined.
This change upgrades our wormhole dependency to the current latest
release. It introduces a fix in rent calculation logic, making Solitaire compatible with
PythNet. This lets us get rid of dedicated rent adjustment logic,
which we also remove in this change.
