refactor: consolidate WebLoginStartResult and WebLoginWaitResult into WebLoginResult

WebLoginStartResult and WebLoginWaitResult were byte-for-byte identical:
both had the same 5 properties (Message, QrDataUrl, Connected, Error,
RawResponse). The method names (WebLoginStartAsync / WebLoginWaitAsync)
already distinguish the two flows semantically, so maintaining two
separate types added no value.

Replace both with a single WebLoginResult class. Update IOperatorGatewayClient,
OpenClawGatewayClient, and the FakeOperatorGatewayClient test stub accordingly.
ChannelsPage.xaml.cs uses both via property access with inferred types and
required no changes.
