New NewProjectDialog: a bare /editor visit (and the New workspace button)
offers a blank workspace or a ready-to-run Blink starter per board family
instead of silently dropping the user into the hardcoded Uno + LED starter.
Boards with a gallery Blink example load it fully wired; the rest get a
fresh board with the on-board-LED sketch. Pro-gated boards carry the PRO
pill and go through the boardGateDecision seam. Shows once per page load;
en/es strings (the other locales fall back to English for now).
