cooper-oai 44f1b0e867 Apply runtime authentication to realtime connections (#60003) ...

## Why

Realtime connections bypassed runtime authentication and reused captured authentication headers for sideband handshakes. They need to honor the selected credential source and its transport policy across call creation, retries, and reconnects.

## What changed

- Use runtime authentication for realtime WebSocket connections, WebRTC call creation, and sideband attachment when enabled for supported OpenAI destinations.
- Resolve authentication on every WebSocket handshake, preserving credential ownership and request scope while generating fresh assertions. Reject authentication failures without falling back to bearer authentication.
- Keep call creation and sideband attachment bound to the selected credentials and account network policy, including when inference uses a different provider.
- Avoid runtime initialization for local marketplace and MCP operations, plugin commands that do not use the remote catalog, and model debugging with a configured catalog.

## Testing

Add coverage for fresh handshake credentials on retries and reconnects, credential and account changes, runtime authentication modes, destination validation, and registration failures.
