Request mandate for customer's payment methods

Coaches and studios can now request a mandate from the client profile if no direct debit or linked payment method is available yet. This can be done via the client's payment methods.

The customer then receives an email with a secure payment link to confirm the mandate. Depending on the chosen payment method, the customer pays a small verification fee, for example €0.01 via iDEAL or a minimum of €0.02 via Bancontact. This verifies the payment method, after which it can be used for future automatic payments.

This makes it easier for coaches and studios to correctly collect payment methods and properly set up subscriptions or recurring payments.
