Align Ultravox Realtime service with OpenAI/Gemini patterns

Browse Source 
- Add InterruptionFrame handling with stop_all_metrics()
- Add processing metrics (start/stop) at response boundaries
- Fix agent transcript handling for voice and text modalities:
  - Voice mode: push LLMTextFrame (append_to_context=False) and
    TTSTextFrame for deltas, skip duplicated final text
  - Text mode: push LLMTextFrame with proper response lifecycle,
    no TTSTextFrame (downstream TTS handles audio)
- Add output_medium parameter to AgentInputParams and OneShotInputParams
- Improve TTFB measurement using VAD speech end time
- Update example with user turn strategies and transcript events
- Add text-only output example (50a-ultravox-realtime-text.py)
