🔧 Zoom Control - FIXED VERSION

✅ Fixes Applied:

X Button Fix: Added pointer-events: none to the iconify-icon element to prevent it from capturing clicks
X Button Fix: Added halt the event to prevent event propagation
Drag Fix: Improved the mousedown handler to properly check for interactive elements using both classList.contains() and closest()

🧪 Test Steps:

Test X Button:
- Click the X button (top-right corner of zoom control)
- ✅ Expected: Zoom control should disappear and "Show Zoom Control" button should appear at bottom
Test Show Button:
- Click the "Show Zoom Control" button
- ✅ Expected: Zoom control should reappear and button should disappear
Test Dragging:
- Click and hold on the grey background of the zoom control (NOT on slider/buttons)
- Move your mouse while holding
- ✅ Expected: Zoom control should move with your mouse
- Release the mouse
- ✅ Expected: Position should be saved (reload page to verify)
Test Slider:
- Click and drag the slider
- ✅ Expected: Slider should move, NOT trigger drag mode

Key Changes Made:

1. Close Button (zoom-control.html:76-81)
   - Added: halt the event
   - Added: style="pointer-events: none;" to iconify-icon

2. Drag Handler (zoom-control.html:26-42)
   - Changed from: event.target.closest('.zoom-slider, .zoom-close-btn, .zoom-reset-btn')
   - Changed to: Multiple specific checks:
     * if target.classList.contains('zoom-slider') exit end
     * if target.classList.contains('zoom-close-btn') exit end
     * if target.classList.contains('zoom-reset-btn') exit end
     * if target.closest('.zoom-close-btn') exit end
     * if target.closest('.zoom-reset-btn') exit end
