Top-level wrapper that renders lock screen (tile grid + PIN pad) when
no tech is signed in, and renders <t t-slot="default"/> otherwise.
Drives the auto-lock countdown via the activity_tracker service +
sends a /fp/tablet/ping heartbeat every 60s while a tech is signed in.
Tiles fetch from /fp/tablet/tiles using the localStorage station id
(set by ShopfloorLanding on QR pair / station picker selection).
State machine for the lock screen body:
loadingTiles → tiles list → tile tapped → PinPad → unlock RPC
↑
onPinCancel → back to tiles
