feat(config): add telemetry and metrics configuration options

- Introduce new environment variables for telemetry and Prometheus metrics in .env.example
- Create example configuration files for Prometheus and Grafana dashboards
- Update main application to utilize new configuration settings for Sentry, audio converter, and proxy
- Enhance channel services to support audio conversion API integration
- Implement middleware for metrics IP whitelisting and basic authentication in routes
