Only for amount 0 then fine leave it enabled for this, but for all other values out of min/max disable the button please since it unavoidably leads to an error state.

Summary: leave it enabled for default 0 state as here alby let's me choose an amount

but disable for all amounts that are not 0 but outside of min/max range as here the anmount is fixed in Alby and the invoice is guaranteed to not be accepted by web app
