Add production deployment with manual approval gate

- Add values-prod.yaml with persistence enabled (20Gi PostgreSQL, 100Gi MinIO)
- Add deploy_prod job triggered on semantic version tags (v1.0.0, etc.)
- Production deployment requires manual approval for safety
- Add integration_test_prod job to verify prod deployment
- Production uses orchard.common.global.bsf.tools hostname
- Trusts main branch (skip re-running all tests for tags)
