Remove auto-visit GPS tracking

Browse Source 
- Removed startVisitTracking / stopVisitTracking functions
- Removed checkProximityToAssets and haversineM
- Removed logAutoVisit and all visit timer logic
- Removed visitTracker UI div on Map tab
- Removed GPS watchPosition call (was polling at ~1-5s intervals)
- Kept server-side /api/visits endpoints (used by heatmap) and one-shot GPS for scan check-in

Reason: GPS auto-tracker can't distinguish machines above/below each other
on different floors.
