feat(kubernetes): enhance configuration and health checks

- Added support for environment variables prefixed with "ES_".
- Updated ReflectorOptions configuration to use nameof for better maintainability.
- Changed the container port from 25080 to 8080 in deployment.yaml.
- Modified liveness and readiness probes to point to new health check paths.
- Introduced a new Kubernetes setting for skipping TLS verification.

BREAKING CHANGE: Health check endpoints have been updated.
