Subject: [PATCH] feat(kiosk): immediate first heartbeat + loading spinner
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Heartbeat slept 60s before first send, so admin Hardware panel showed
"—" right after pairing/boot. Reorder: fire once, then sleep.

Add a GTK spinner under the logo on the idle/pairing screens so users
see the kiosk is alive and working rather than staring at a static
splash.
