fix: update current service in store before navigating to dashboard

[KitAndrew]

When clicking a service name in the ServiceList component, the application navigates to the service dashboard. However, the instance selector on the target page might initialize before the URL parameters are fully processed, potentially leading to an incorrect instance list (e.g., showing all instances instead of those belonging to the selected service).

This commit explicitly sets the current service in the selectorStore before triggering the route change. This ensures the global state is synchronized and the target page components have the correct context immediately upon mounting.
