Subject: [PATCH] fix: prevent full page reload when clicking Main Dashboard
 button

Intercept .nav-dashboard-btn clicks to perform SPA-style navigation
instead of a full page reload. After switchMode() updates the URL to
/?mode=<x> via pushState, clicking href="/" previously caused a round-
trip reload. Now the click handler stops active scans, destroys the
current mode, shows the welcome overlay, and pushes '/' onto history.

Also update popstate to restore the welcome page when navigating back
to '/' with no mode param.
