Widen claims library container for better card spacing

Increased max container width from 1152px to 1920px and enhanced responsive padding to give cards more breathing room across all screen sizes.

Changes:
- Container max-width: 1152px (6xl) → 1920px (custom)
- Responsive padding: px-5 → px-6 (mobile), px-8 (md), px-12 (lg)
- Result: Cards are wider and less cramped, better use of screen space

This allows the 5-column grid to properly utilize ultra-wide displays while maintaining comfortable card proportions.
