refactor: remove OpenTelemetry Collector and integrate telemetry service

- Deleted the otel-collector job from GitHub workflows and related deployment configurations.
- Updated Helm charts to remove references to the OpenTelemetry Collector, including its deployment and service definitions.
- Added gRPC server functionality directly in the telemetry service to handle telemetry ingestion.
- Updated environment variables and Docker configurations to reflect the removal of the OpenTelemetry Collector.
- Adjusted telemetry service to support both HTTP and gRPC protocols for telemetry data.
