One customer invoice with its lines, payments and matched bank transactions.

Pennylane API: https://cotlet.dev/docs/api/pennylane.md

`GET https://cotlet.dev/api/v1/pennylane/invoices/{invoice_id}/customer-invoice`

Access: read.

Returns one invoice with every line, the payments Pennylane recorded and the bank transactions matched to it. A payment is one made through Pennylane, such as the payment link; a matched transaction is one made outside Pennylane, such as a bank transfer. An invoice sent through e-invoicing also returns its e-invoicing status.
