[ApplicationVerification] Send verification E-Mails after creating an application

[sarahsporck]

Is your feature request related to a problem? Please describe.
The referenced organizations of an application need to be informed and verify an application.

Describe the solution you'd like
When a user submits an application and it is stored in the DB, the referenced organizations should each receive a verification e-mail. Think about the text. There already exists a utility to send e-mails in the backend.

[EDIT] The url should be encoded, so that outlook can pick it up. See: #828

@sarahsporck What needs to be done to unblock this task from #837? I think, we only need to agree on a route, so that we can generate the links to the correct URL on which the organizations can verify/reject an application?

[sarahsporck]

Exactly. I am currently still struggeling to decode on the route in the other task. I guess what makes the most sense is sth. Like /verifizieren/{application_verification_id}?accessKey={accessKey}. Do you agree?

[michael-markl]

If it makes it any easier, we can also do /verifizieren/{application_verification_id}/{accessKey}.
However, we might actually want to rename verifizieren => antrag-verifizieren?

[sarahsporck]

Hmm. As far as I know there is no specific ruling when to use path and query params. Generally, the path leads to a specific resource and then the query filters/sorts/... the resource. Therefore, I'd but the access key into the query param. Are you alright with /antrag-verifizieren/{application_verification_id}?accessKey={accessKey}?

[michael-markl]

Sorry for the late objection: As I wrote in your current PR #857 , we should probably avoid externalizing our interal ids. Also, I originally designed the accessKey to be unique. So we should be able to just omit the application_verification_id in the link and go with either /antrag-verifizieren/{accessKey} or /antrag-verifizieren?accessKey={accessKey} whatever suits you better. Feel free to speak against this :D
