Dylan Hurd 4e9a1a9073 Preserve HTTP fallback for delegated sessions (#38681) ...

## Why

Responses WebSocket fallback is session-scoped. A delegated session created
after its parent switched to HTTP could otherwise make another WebSocket
connection attempt.

## What changed

Disable WebSocket support for a delegated session when the parent session has
already fallen back to HTTP.

## Testing

Add a guardian review regression test that verifies only the parent's initial
WebSocket attempt occurs and the guardian request uses the HTTP response path.
