fix: rename K8s env vars to EXECUTE_ prefix for execute-service

- ConfigMap keys: DB_HOST -> EXECUTE_DB_HOST, DB_PORT -> EXECUTE_DB_PORT, etc.
- Deployment secrets: DB_USER -> EXECUTE_DB_USER, DB_PASSWORD -> EXECUTE_DB_PASSWORD
- Helm configmap: add EXECUTE_DB_* keys alongside legacy POSTGRES_* keys
- Base deployment: add EXECUTE_DB_USER/PASSWORD from secrets
