Improve snackbar styling and fix business switching

Snackbar Improvements:
- All snackbars now have colored backgrounds (green/red/orange/blue)
- Added icons to snackbar messages (check_circle, error, warning, info)
- Floating behavior with bottom margin to avoid obscuring action buttons
- Consistent styling across menu_browse, cart_view, and login screens

App State Fixes:
- Clear cartItemCount when switching businesses (setBusiness, setServicePoint, setBusinessAndServicePoint, clearAll)
- Prevents stale cart count showing after switching restaurants
