Two registry-level services:
tech_store Shared reactive state holding currentTechId after a
successful PIN unlock. Other components subscribe via
useService("fp_shopfloor_tech_store") and read
currentTechId to inject into action RPCs. setTech(id, name)
on unlock; lock() on auto-lock / Hand-Off.
activity_tracker Document-level event tracker for pointerdown / touchstart
/ keydown / visibilitychange. Mouse-move alone deliberately
EXCLUDED — a tool resting on a tablet would otherwise keep
the session alive indefinitely. Public API:
bump(), getSecondsUntilLock(), getWarnThresholdSec()
Reads thresholds from ir.config_parameter at start +
every 5 min (so manager edits propagate within a shift).
