Celia Chen 142360dac8 Honor configured proxies for realtime WebSocket connections (#47101) ...

## Why

Realtime WebSockets connected directly, bypassing the configured proxy policy for Voice's WebRTC sideband.

## What changed

Pass the configured `HttpClientFactory` into `RealtimeWebsocketClient` and connect through the shared `WebSocketConnector`. Add support for supplying an existing Rustls configuration to preserve custom CA handling and Windows platform trust.

## Testing

Add an integration test that enables `respect_system_proxy`, starts a WebRTC conversation, and verifies that the sideband establishes its session through an HTTP `CONNECT` proxy and closes successfully.
