#232 Payment document linkage

* adds error message on intervention view if a payment has been added but no document has been uploaded yet
* adds same check to quality checker, meaning no intervention can be recorded which has a payment but no document
* adds trigger for sending data to egon on uploading a document in case of an already existing payment
* adds translations
