- Fix TestAnalyticsHandler_ErrorHandling to use proper in-memory database
instead of nil database which caused nil pointer dereference
- Update handleGetCorridors to return corridors wrapped in {corridors: [...]}
for consistency with frontend expectations from crowdflow.js

- 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.
Confirm AnomalyDetector initialization in main(), wire anomaly event
broadcasts to dashboard WS as alert messages, and verify all security
mode endpoints (arm/disarm/status) return correct JSON with persistent
state across restarts.

- AnomalyDetector initialized and running in main() with periodic updates
- Anomaly events pushed to dashboard WS feed as 'alert' messages
- GET /api/anomalies?since=24h lists recent anomaly events
- POST /api/security/arm + /api/security/disarm endpoints
- GET /api/security/status returns armed, learning_until, anomaly_count_24h
- Arm/disarm state persists via learning_state SQLite table

Add trajectory accumulation, directional flow maps, and dwell time
hotspot visualization for occupancy pattern analysis.
Backend:
- FlowAccumulator records trajectory segments and dwell time in SQLite
- REST endpoints for flow map, dwell heatmap, and detected corridors
- Bresenham rasterization for flow vector aggregation
- Connected component analysis for corridor detection
Frontend:
- Pattern controls in dashboard sidebar (flow, dwell, corridors toggles)
- Time filter dropdown (7d, 30d, all time)
- 3D visualization with ArrowHelper for flow, PlaneGeometry for heatmaps
- Pulsating animation on flow arrows
