Massively improve responsive layouts for smaller screens

Added breakpoints:
- 900-1399px: Tablet with sidebar, card layout
- 600-899px: Small tablet, compact cards with actions
- 480-599px: Large phone, hidden sidebar, mobile filter toggle
- Below 768px: Full mobile optimization

Card improvements:
- Better touch targets (48px buttons)
- Clearer visual hierarchy
- Active states for touch feedback
- Priority border indicators
- Clean meta information layout

Mobile improvements:
- Removed card gaps for cleaner list appearance
- Larger fonts for readability
- Better spacing and padding
- Touch-friendly action buttons
