The MeshCore founders' givealittle fundraiser has closed (reported on
Discord by jason000008), so the banner was sending visitors to a page that no
longer takes donations. Removed the markup, its styles and its dismiss script
together.
The corner button rails need no change: .fab-rail already falls back to
top:16px, which is exactly what the banner script set once it was dismissed,
so everyone now sees the layout returning visitors already had.
