Fix two critical issues with the trophy abacus system:
1. Hero abacus appearing on all pages:
- Root cause: HomeHeroProvider now wraps all pages globally
- Solution: Use pathname check to detect actual home page routes
- Only show hero mode on: /, /en, /de, /ja, /hi, /es, /la
2. Z-index conflicts causing layering issues:
- AppNavBar had hardcoded z-index: 1000 (DROPDOWN layer)
- Should use Z_INDEX.NAV_BAR (100) for proper layering
- Tooltip had z-index: 50, should use Z_INDEX.TOOLTIP (1000)
This ensures:
- Hero abacus only appears on home page, not all pages
- Trophy abacus (z-index 30001) appears above ALL content
- Nav bar and tooltips use correct z-index constants
- No stacking context conflicts
