Backend request/response structs used camelCase JSON tags while the
rest of the codebase uses snake_case (from Ent ORM entities). This
caused field name mismatches — notably the admin refund deduct_balance
field was silently ignored.
Backend: changed all camelCase JSON tags in payment handler/service
structs to snake_case (CreateOrderRequest, CreateOrderResponse,
CreatePlanRequest, UpdatePlanRequest, CreateProviderInstanceRequest,
UpdateProviderInstanceRequest, AdminProcessRefundRequest, RefundResult).
Frontend: updated all API call payloads and response field accesses
to use snake_case, removed manual camelCase conversion in
buildPlanPayload, toggleForSale, provider dialog emit, etc.
