feat v1.41.0: kiosk mode for wall tablets and TVs

- kiosk: true — header hidden, editors hard-blocked, full-height stage;
  full View interactivity preserved (live states, glow, taps, locks)
- swipe between spaces at 1:1 (swipeTarget pure helper, wrap + dots
  indicator), pan wins while zoomed, double tap resets zoom
- cycle: N auto-carousel with 60 s pause after any touch (TV/burn-in)
- per-SCREEN size multipliers (icons x0.5-3, room-card font) in
  localStorage via a 3 s long-press popover; clampScale helper
- GUI editor fields, README wall-tablet recipe, +2 unit tests (111),
  smoke_kiosk.mjs (12 checks); TESTING/CHANGELOG same-commit
