Code Review

This pull request introduces OpenTelemetry auto-instrumentation to Athenz UI, which is a great step towards better observability. The implementation is solid, but I have a few suggestions to enhance its robustness and align it with best practices. My feedback includes aligning OpenTelemetry package versions for stability, ensuring secure connections are enforced when configured, adding resource attributes for better telemetry identification, and implementing a graceful shutdown mechanism to prevent data loss.
