Fix receipt page display issues

## Issues Fixed:

1. **Better Icon**: Replaced bell icon with leaf/plant icon for carbon offset
   - More appropriate visual representation

2. **Currency Formatting**: Added thousand separators to all amounts
   - Added formatCurrency() helper function
   - Total now shows "$13,414.12" instead of "$13414.12"
   - Applied to base amount, processing fee, and total

3. **Print Functionality**: Fixed empty page printing
   - Removed "no-print" class from outer wrapper
   - Only interactive elements (buttons) hidden when printing
   - Receipt content now prints properly

4. **Status Display**: Shows "Confirmed" immediately after payment
   - Uses Stripe session.paymentStatus for just-completed payments
   - Falls back to order.status for older orders
   - Prevents showing "Processing" when payment is already complete

## Technical Changes:
- CheckoutSuccess.tsx (line 27-32): Added formatCurrency helper
- CheckoutSuccess.tsx (line 120-121): Use Stripe payment status
- CheckoutSuccess.tsx (line 145): Removed no-print from wrapper
- CheckoutSuccess.tsx (line 208-210): Changed to leaf SVG icon
- CheckoutSuccess.tsx (lines 228, 234, 241): Use formatCurrency()
