Pull Request Title: feat: Payments based dunning
Pull Request Description:
Related to #26969
Create dunning for all overdue payments of a customer. We use a table similar to the payment schedule in sales invoice to pull all overdue scheduled payments into the Dunning.
- Rate of Interest is the same for all overdue payments.
- Interest amount is calculated for each overdue payment.
- Dunning Fee is applied only once per dunning.
Changes in accounting
- Dunning amount will no longer be booked to receivables. The reason is that the dunning amount is not paid in many cases / is only intended as a warning. If paid, the dunning amount will be recorded as additional income in Payment Entry. See here and here for further reading (in german).
