feat: support annotations on Deployment/StatefulSet in Helm chart

Add a top-level `annotations` value that gets applied to the main
Appsmith Deployment or StatefulSet metadata. This enables use cases like
Stakater Reloader (`reloader.stakater.com/auto: "true"`) and other
annotations that must live on the workload resource itself rather than
on pods. Also wires up `commonAnnotations` to the workload resource,
which was previously missing.
