product-service chart: split /health & /ready probes, externalize config

[devin-ai-integration]

Summary

Updates the product-service Helm chart to match the newly containerized Product service (see quickapp-microservices companion PR): distinct liveness/readiness probes, container port 8080, and env-var/secret-based configuration instead of hardcoded values.

Probes — healthCheck in values.yaml split from a single path/port into:

healthCheck:
  liveness:  { path: /health, initialDelaySeconds: 15, periodSeconds: 10 }
  readiness: { path: /ready,  initialDelaySeconds: 5,  periodSeconds: 5 }

deployment.yaml now points livenessProbe → /health and readinessProbe → /ready.

Ports — new containerPort: 8080 (matches the image's ASPNETCORE_HTTP_PORTS). service.port stays 5004 (stable cluster address); Service targetPort now resolves to containerPort.

Config externalization — deployment injects env vars; DB password is pulled from an existing Secret rather than stored in values:

env:
  - ASPNETCORE_ENVIRONMENT / ASPNETCORE_HTTP_PORTS
  - ConnectionStrings__DefaultConnection: "Host=...;...;Password=$(DB_PASSWORD)"
  - DB_PASSWORD: valueFrom.secretKeyRef(name=product-service-db, key=password)

New config.database.* (host/port/name/username/existingSecret/passwordKey) and extraEnv: [] values. No credentials in the chart.

Verification

helm lint charts/product-service                                  # passes
helm template product-service charts/product-service -f environments/{dev,staging,prod}/values.yaml   # renders
yamllint charts/product-service/... environments/                 # only pre-existing document-start warnings
