- Fix Viz3D exports to include flow visualization functions
- Export setFlowLayerVisible, setDwellLayerVisible, setCorridorLayerVisible
- Export setFlowTimeFilter, setFlowData, setDwellData, setCorridorData
- Remove duplicate setDwellLayerVisible function definition
This completes the crowd flow visualization feature that was
already implemented in the backend (flow.go) and frontend
(crowdflow.js, viz3d.js) but had missing exports in the Viz3D module.
Added tests for:
- Auto-away activation when all registered BLE devices absent for 15+ minutes
- Auto-disarm triggering when registered BLE device returns with strong RSSI
- Manual override pausing auto-away detection
- System mode GET/PUT REST API endpoints
- Edge cases: no registered devices, weak BLE signals, unregistered devices
