chore(fusion_plating_shopfloor): bump 19.0.30.1.0 for Phase 6.2 — lock screen

Frontend lock screen ships:
- tech_store + activity_tracker shared OWL services
- FpPinPad, FpIdleWarning, FpPinSetup components
- FpTabletLock outer wrapper
- Wired into Landing/Workspace/Manager + Hand-Off button in each header
- fp_tablet_pin_setup client action for Preferences self-service
