[FIX] account(_payment): display `Pay Now` btn only for out invoices

1. Only facture client should see pay now*, not credit note etc
2. Pending transaction should be handled like:
   * Manual & (wire) transfer pending transaction should display pending but still
     show the pay button
   * Other pending transaction should display pending & hide the button
   * Exception: A wire or manual pending transaction should have the status "Waiting for payment"
                and not pending in /my/invoices status

* and "amount due" aswel so clients won't complain about the payment arriving too late
