Supporting data customers

Added customer supporting data to manage customers and quickly auto-fill buyer information when sending documents.

You can now manage customers as supporting data and reuse them while sending invoices and credit notes.

Customers API: Added endpoints to list, retrieve (by internal ID or externalId), upsert, and delete customers for a team.
Dashboard customers page: Added a dedicated Customers page in the dashboard to create and manage your customer list.
Send-document autofill: When sending an invoice or credit note, you can select a customer to auto-populate buyer/seller details (including self-billing flows) and automatically fill the recipient Peppol ID from the customer's saved Peppol addresses.

More information can be found in the API reference.
