fix(kiosk): a finished timer stays in its pane and goes with one tap; its close button is clear of the dashboard's; kiosk 0.2.2

The problem

When a timer finished, the kiosk page turned its card into a full-screen layer. Opened from the dashboard ("Talk to Crow", the session overlay), this caused three problems:

• The card's close button sat in the frame's top-right corner, directly under the overlay's own close button. Measured at 412x915: the card's button was at x 351-407, y 5-61 and the overlay's at x 360-404, y 8-52. The overlay's button is drawn above the frame, so a tap there closed the whole overlay.
• The full-screen layer covered the bird and the "Tap to talk" button, so you couldn't say "stop" either.
• The timer stays on the server until it is dismissed, so it showed "Time's up" again every time you reopened the overlay.

The fix

• A finished timer now stays in its window pane instead of covering the page. While it is ringing, the page background takes a teal tint, so the alert can still be seen from across the room on a wall display.
• One tap anywhere on a finished timer dismisses it. It sends the same server event as its close button, so it does not come back on reopen. A short "Tap to dismiss" line (English and Spanish) says so. Repeated events from one gesture (swipe, close button, card tap) dismiss it once, not twice.
• In session mode a window's close button sits at the card's top-left corner. The overlay's button moves down with the phone's status-bar inset, which the frame cannot read, so only a separate column guarantees the two never overlap.
• The talk button sits above the windows.
• Kiosk 0.2.2. The turn-check test now reads the version from the manifest instead of hardcoding it.

Tests

• New live test tests/kiosk-timer-done-live.test.js runs in a private headless browser. It covers the session overlay at 412x915, 915x412 and 1280x800, and a paired display at 800x480 and 412x915. It checks with real hit-testing that the card's close button, the bird and the talk button are each reached by a tap at their center, and that no column is shared with the overlay's button. A real click on the card dismisses it once. Against the previous page code every case fails.
• New view tests in tests/kiosk-page.test.js: tap-to-dismiss, the dismiss happening only once, the page tint, and the CSS rules.
• Full suite: 7708 pass, 0 fail, 1 skipped. Public-hygiene and registry checks are clean.
