Interview contact modal

[jochenklar]

This PR adds the possibility to send questions though a contact form directly from the interview. It contains:

• PROJECT_CONTACT and PROJECT_CONTACT_RECIPIENTS settings
• different templates to customize emails and help texts
• API endpoints to create the message and the subject, which then can be edited by the user, and to send it via email
• fetchContact, sendContact, closeContact actions and a contactResolver for the Redux store
• QuestionContact (the button) and Contact (the modal) components

Resolves: #502

maybe:

Suggested change

	If you have questions about a question or other inqueries to support, you can use the
	If you have a question or feedback please get in touch with us, you can use this form to send an email to the {{ request.site.name }} support"

or is it meant to be overwritten in the rdmo-app anyway?

A nice-to-have feature request for this PR would be to have this setting to be editable in the admin UI..
That would open a whole other feature of having settings in the Django Models right?

[jochenklar]

yes, lets not start this now. we would need a settings or config model and also some good way to cache the entries there. the nice thing about django.conf.settings is that its super fast.

also: settings by site? 🤯

[MyPyDavid]

alright, yeah settings is nice and fast ;)
of course it would be by site and maybe role-based permissions, etc..
