style(installer): match progress header to overlay & token-size failure buttons

Port the nous-girl BrandMark (asset + component) into the Tauri shim and give
the progress screen the same brand + title + description structure as the
desktop install overlay. Drop the failure screen's oversized lg/outline
buttons for the shared default token + a quiet text-link "Open logs".
