✨ (helm/v2-alpha): Make webhook and metrics ports configurable

- Add configurable webhook.port (default: 9443) and metrics.port (default: 8443) in values.yaml
- Keep health probe port fixed at 8081 (not exposed in values)
- Add certManager section to values.yaml (always present, enabled based on webhooks)
- Fix pre-existing test failures (incorrect assertions for certManager and manager keys)
- Add comprehensive unit tests for port configuration with default and custom values
