Fix mobile bottom nav consistency and ticket view width

Mobile bottom nav:
- Added nav-label class to all text labels in JS
- Fixed icon sizing (20px fixed height)
- Fixed label sizing (10px for all)
- Equal width columns (25% each)
- Changed gear emoji from ⚙️ to ⚙ for consistency

Ticket view mobile:
- Removed all borders from ticket container
- Removed decorative corners on mobile
- Reduced nested padding significantly
- ascii-frame-inner now 0.75rem padding (was 1rem)
- Nested ascii-frame-inner only 0.5rem
- detail-group full-width has no padding
- Content goes edge-to-edge
