Fix Helm chart self-hosting footguns

Address the highest-impact Kubernetes chart issues from #1245.
Align PG_ADDR with postgresql.host/port, wire
OAUTH2_SERVER_SIGNING_KEY, add early validation for required
base64 and PEM secrets, and isolate the main service/deployment
with component labels so Chrome pods are not selected by server
traffic.

Update chart values and documentation to clarify required secret
formats, managed PostgreSQL prerequisites, ACME account key
persistence, and current Azure Blob compatibility caveats for S3
proxy deployments.
