Reclassify debt transfers and MACH/Servipag card payments as internal

Debt repayments (TRASPASO A/DE DEUDA, TRASPASO POR CIERRE DE CUENTA) are
payments against an international credit card — the purchases already
happened on that card, only fees/interest are new costs. Reclassify from
expense → card_payment (internal) so they show in Cycles, not Spending.

Same for MACH Comercios→Servipag and PAGO EN SERVIPAG.COM* which are
Rappi card payments routed through Servipag, not utility bills.
