Fix WebRTC Streaming Issue in Home Assistant App (WebView Beta 143)

[jonnynch]

As a webview beta user, my phone webview version is 143.0.7499.15.
Streaming from my Nest Doorbell does not work in the Home Assistant mobile app, while it works correctly in both Chrome and Firefox.

Error Observed:

Failed to connect WebRTC stream: Failed to execute 'setRemoteDescription' on 'RTCPeerConnection': Failed to set remote answer sdp: Incompatible send direction

Home assistant issue has been raised
Reference: home-assistant/frontend#27781

This issue is related to a recent change in Chromium that enforces stricter validation on the answer SDP direction.
Reference: https://webrtc-review.googlesource.com/c/src/+/413340/7/pc/sdp_offer_answer.cc#b313

Fix:
This PR extends the SDP direction fix to all browsers, not just Chrome.
The test case has been updated accordingly.

Verification:
Streaming has been tested and confirmed working in:
Home Assistant mobile app (WebView 143.0.7499.15)
Chrome 142.0.7444.48
Firefox 144.0.2
