feat: enhance zoom and print button UX

Print Button Improvements:
- Hover shows white background with green icon (was green bg + white icon)
- Applied to all print buttons: fixed, action bar, and menu
- Default state remains dark gray with white icon

Zoom Control Improvements:
- Text now 100% white (was 70-95% opacity) for better readability
- Increased font sizes: labels 0.95rem (was 0.8rem), current value 1.05rem (was 0.9rem)
- Hover zoom toggle button highlights zoom control with blue glow shadow
- Active zoom button uses semi-transparent blue rgba(52, 152, 219, 0.5) instead of solid

Z-Index Fix:
- Hamburger menu now appears above fixed buttons (z-index: 1000 vs 999)
