Move server rack inline styles to CSS classes

Replace the per-element inline positioning in createServerRack()
with rack-*-pos utility classes in style.css. Also stop drawing
a random switch face brand from a list (only Framework ships)
and simplify the hero-click terminal toggle to use the shared
expand/collapse helpers.
