feat(billing): add missing payment methods and configurations
- Added migration to include global payment method configurations for Stripe and PayPal (both disabled). - Ensured existing payment methods like bank transfer and manual payment are correctly configured. - Added database constraints and indexes for improved data integrity in billing models. - Introduced foreign key relationship between CreditTransaction and Payment models. - Added webhook configuration fields to PaymentMethodConfig for future payment gateway integrations. - Updated SignUpFormUnified component to handle payment method selection based on user country and plan. - Implemented PaymentHistory component to display user's payment history with status indicators.
