registry-deploy-on-push

This scenario verifies the Cloudly registry to Coreflow deploy-on-push path.

Assertions:

Cloudly starts with isolated MongoDB and S3 helpers.
Coreflow authenticates with the cluster machine token.
Docker login and push to Cloudly's OCI registry work.
Cloudly records the pushed image digest and pushes config to connected Coreflow.
Coreflow creates the workload service from the registry-backed image.
Coretraffic receives the route config and serves HTTPS traffic to the workload.
Re-pushing latest with a new digest recreates the Docker service.
