Add test recordings to all Agent telemetry tests that have OpenAI only network calls

[dargilco]

Agent telemetry tests that have network calls from both AIProjectClient and OpenAI client are still skipped in the pipeline, since this is not yet supported.

With this change, we have many more Agent telemetry tests running in the pipeline:

Thank you @M-Hietala for all these tests.

Also, unrelated, run 'black' tool to fix formatting in samples.

Pull request overview

This PR enables test recording for Agent telemetry tests that previously only made OpenAI network calls. The changes replace the standard recording decorators with httpx-specific decorators and remove skip markers that were blocking execution of these tests.

Key changes:

• Replaces @recorded_by_proxy with @recorded_by_proxy_httpx for synchronous tests and @recorded_by_proxy_async with @recorded_by_proxy_async_httpx for asynchronous tests
• Removes @pytest.mark.skip decorators from 58 test methods across three test files
• Updates test assets tag to reflect new recordings
