Add delivery order badges and optimize list performance

Enhance delivery list UI with sequential order badges and improve scrolling
performance with faster animations for better user experience.

Delivery Order Badge:
- Add 60x60px status-colored square badge showing delivery sequence number
- Position badge to the left of vertical status bar for clear visual hierarchy
- White text (26px, bold) centered in badge
- Automatically displays deliveryIndex + 1 (first delivery = 1, second = 2, etc.)
- Status color matches delivery state (green for completed, gray for pending, etc.)
- 10px border radius for modern appearance

Layout Enhancements:
- Sidebar expanded from 360px to 420px to accommodate order badges
- Vertical centering of row elements for better visual balance
- Maintains optimized spacing: badge (60px) + gap (12px) + bar (6px) + gap (16px) + content
- Full list scrolling restored (removed 4-item limit)

Animation Performance:
- Stagger animation delay reduced by 90% (50ms to 5ms)
- Fast stagger: 30ms to 3ms for ultra-responsive scrolling
- Delivery items appear almost instantly when scrolling
- Total animation time for 20 items: 500ms to 100ms
- Maintains subtle stagger effect while feeling immediate

User Experience Improvements:
- Clear visual indication of delivery order in route
- Faster perceived loading when scrolling through deliveries
- Better readability with larger, prominent order numbers
- Consistent status color coding across badge and accent bar
