Azure TTS _handle_canceled was putting None (the normal completion signal) into the audio queue for all cancellation reasons, so run_tts treated errors identically to success—silently producing no audio. Now error cancellations put an Exception marker in the queue, which run_tts converts to an ErrorFrame. Azure STT had no canceled event handler at all, so auth failures, network errors, and rate-limit cancellations were invisible. Added _on_handle_canceled which pushes an ErrorFrame upstream via push_error. Fixes pipecat-ai/pipecat#3892

- Fixed Azure TTS and STT services silently swallowing cancellation errors (invalid API key, network failures, rate limiting) instead of propagating them as
ErrorFrames to the pipeline.
