Add shared iDEAL payment method and reuse images

Introduce a single $payment_method_ideal instance with name, description and image paths and register it earlier in Plugin::init. Reuse its images for the direct-debit-ideal payment method instead of duplicating the image array, and remove the later duplicate iDEAL block. This deduplicates code and ensures consistent iDEAL/Wero branding assets while keeping existing behavior.
