In single-model (non-router) mode the server always has its model loaded and the /models/load endpoint does not exist. isModelLoaded only checks routerModels, which is empty outside router mode, so isActiveModelLoaded was always false there. When not in router mode, treat as loaded so the gauge hide the load prompt.

Pull request overview
Fixes the context gauge behavior in WebUI when connected to a single-model (non-router) server, and improves UX by persisting whether “Token usage details” is expanded across page reloads.
Changes:
- Treat the active model as “loaded” when not in router mode, preventing the UI from showing a “Load model” action that calls a non-existent endpoint in single-model mode.
- Add a dedicated localStorage key for the context gauge details open/closed state.
- Persist the context gauge “Token usage details” open state via the existing
persisted()helper.

Overview
Webui bugfix for single-model mode usage
Additional information
In single-model (non-router) mode the server always has its model loaded and the /models/load endpoint does not exist. Current context gauge report the model as unloaded and showed a "Load model" button that will hit /models/load and errored.
See below:
Cause: isModelLoaded only checks routerModels, which is empty when not in router mode, so isActiveModelLoaded always false there.
Fix: When not in router mode, treat as model loaded so the gauge hide the load prompt.
Second commit is to persist the context gauge "Token usage details" open state to browser local storage for better UX experience.
