Description
AsyncRealtimeConnectionManager.send() / RealtimeConnectionManager.send() call json.dumps(event) on dict payloads, but post-connect connection.send() uses maybe_transform() which strips Omit/NotGiven.
Repro:
manager = client.realtime.connect(model="gpt-4o-realtime-preview")
manager.send({"type": "response.cancel", "event_id": omit})
# TypeError: Object of type Omit is not JSON serializable
PR incoming with regression test.

Research direction
Start with AsyncRealtimeConnectionManager.send() and RealtimeConnectionManager.send(), then compare their json.dumps(event) path with post-connect connection.send() and maybe_transform(). Reproduce the Omit payload shown in the issue and add the mentioned regression test; done means pre-connect sends no longer raises the serialization error.
