iOS remote client: native UIKit surface, WS logging, client-side layout persistence

- Add remote-client-ios: full native UIKit app with Objects/View/UILayout/Functions pattern
- Widget hierarchy: BaseWidget → Fader, Toggle, Transport, Title, Feedback, LogWidget
- LoggingVC: child VC embedded in LogWidget for live WS message inspection
- Codable model: ModelPresetLoadToRemoteDevice with snake_case decoder strategy
- Layout persistence: UserDefaults keyed by preset_uuid, fully client-side
- WS logging: dedicated WS In/Out floating panels on desktop app
- Remove HTTP server and JS client (replaced by native iOS app)
- Add Xcode noise to .gitignore (xcuserstate, xcuserdata)
