Verification helpers shared by the payment-method modules
(MPP.Methods.EVM, MPP.Methods.Tempo, MPP.Methods.Stripe).
These are small, method-agnostic building blocks. require_config/3 takes a
human-readable method label so its error message names the calling method.

@spec parse_charge_amount(String.t()) :: {:ok, integer()} | {:error, MPP.Errors.t()}
Parse a charge amount string into an integer.
Returns {:ok, integer}, or a :verification_failed error when amount is
not a valid integer string.
@spec require_config(map(), term(), String.t()) :: {:ok, term()} | {:error, MPP.Errors.t()}
Fetch a required key from a method's config map.
Returns {:ok, value}, or a :verification_failed error naming the method via
