[FIX] point_of_sale: pass event on the input event handler

During the forward port of the following PR:
https://github.com/odoo/odoo/pull/127730, the event was not passed to the input
event handler, which causes an error when the user tries to enter a new value
for the the other payment methods.

This commit appropriately passes the input event to the handler.
