fix(newos4): the three glyph-only switch buttons now say what they do (v4.6.165)

Asked "how do I switch?", I checked all six modes and found the controls were already uniform in
function — every mode calls `api.exec('ui picker')` — but not in labelling:

  easy       ⇄ Change view
  chat       ⇄ Style
  workspace  ⇄ Style
  studio     ⇄          <- glyph only
  commander  ⇄          <- glyph only
  cockpit    ⇄          <- glyph only

An unlabelled ⇄ on a phone is a guess. The three bare ones now carry
title="Change view — pick another interface" and aria-label="Change view", which api.el() forwards
via setAttribute. Verified on the served build: the snapshot reads `button "Change view"` in studio,
and clicking it opens the picker with all seven options (six modes + "Keep the classic terminal").

No behaviour change — same handler, same picker; the control is now discoverable and announced by
screen readers.
