Fix crypto payment status display and USD conversion in payment history

STATUS DISPLAY IMPROVEMENTS:
- Set payment status to underpaid-refunded/expired-refunded immediately when refund is determined
- Status now reflects refund eligibility rather than waiting for refund execution
- Added confirmed-overpaid-refunded status mapping for UI display

PAYMENT HISTORY ENHANCEMENTS:
- Added USD conversion display for received amounts using locked exchange rate
- Fixed TypeError by properly handling float * Decimal multiplication in templates
- Added refund_tx_hash to payment data for refund status differentiation
- Show "Refund pending" vs "Refund completed" messages based on refund_tx_hash presence

USER EXPERIENCE IMPROVEMENTS:
- Clear messaging about 10-confirmation requirement for refunds
- Immediate status feedback when underpayment/expired payment is detected
- Proper distinction between refund eligibility and refund completion
- Enhanced refund status explanations with restocking fee information

This ensures users see accurate payment status immediately rather than confusing
"Payment Received" labels when their payment is actually being refunded.
