Issue with azure open ai resource

Hi.

we have got this issue. Whenever the page load in local environment I got this issue. I followed the same from the github repo.

` File "C:\MyWorkspace\Python\aisearch-openai-rag-audio-main\.venv\lib\site-packages\aiohttp\web_protocol.py", line 452, in _handle_request
resp = await request_handler(request)
File "C:\MyWorkspace\Python\aisearch-openai-rag-audio-main\.venv\lib\site-packages\aiohttp\web_app.py", line 543, in _handle
resp = await handler(request)
File "C:\MyWorkspace\Python\aisearch-openai-rag-audio-main\app\backend\rtmt.py", line 226, in _websocket_handler
await self._forward_messages(ws)
File "C:\MyWorkspace\Python\aisearch-openai-rag-audio-main\app\backend\rtmt.py", line 193, in _forward_messages
async with session.ws_connect("/openai/realtime", headers=headers, params=params) as target_ws:
File "C:\MyWorkspace\Python\aisearch-openai-rag-audio-main\.venv\lib\site-packages\aiohttp\client.py", line 1194, in __aenter__
self._resp = await self._coro
File "C:\MyWorkspace\Python\aisearch-openai-rag-audio-main\.venv\lib\site-packages\aiohttp\client.py", line 848, in _ws_connect
raise WSServerHandshakeError(
aiohttp.client_exceptions.WSServerHandshakeError: 401, message='Invalid response status', url=URL('https://xxxx.openai.azure.com/openai/realtime?api-version=2024-10-01-preview&deployment=gpt-4o-mini-realtime-preview')`

Start in app/backend/rtmt.py at _forward_messages around line 193 and reproduce the local page-load failure. Inspect the headers and params used for the /openai/realtime websocket against the Azure OpenAI resource and deployment; done means the websocket handshake succeeds without the 401 response.
