📊 feat: Helm Chart Port Flexibility and MongoDB Update (#9750)

- Update MongoDB chart dependency from v16.3.0 to v16.5.45
- Add explicit containerPort configuration with fallback to service.port
- Standardize port references in health probes to use explicit port numbers
- Add targetPort and containerPort fields to service configuration
- Include service type options as inline comment for better clarity

These changes improve the Helm chart's port management flexibility and
bring the MongoDB dependency up to date with the latest stable version.
