Split CI testing into parallel jobs for OpenTelemetry

- test_without_opentelemetry: Run baseline tests without OpenTelemetry
- test_with_opentelemetry_and_coverage: Run comprehensive tests with OpenTelemetry enabled and measure coverage
- Both jobs run in parallel for faster CI execution
- Coverage is measured only on OpenTelemetry-enabled run to capture additional code paths
- Updated pages job dependency to use the new coverage job
