Add machine map editor and fix machine map display

- Create machine_map_editor.asp for bulk position editing
  - Draggable Leaflet markers for repositioning machines
  - Sidebar with filterable machine list
  - Pending changes tracking with save/reset functionality
  - Proper Y-axis coordinate conversion (2550 - top)

- Update machine_map.asp
  - Reduce marker size from 20px to 12px to reduce overlap
  - Filter out network devices (16-20) and PCs (33+) from display
  - Show equipment only (machinetypeid 2-15)

- Add updateMachinePositions API endpoint in api.asp
  - Accepts JSON array of position changes
  - Updates mapleft/maptop for multiple machines
