Give permission to see Allergies for Event to Responsible Group

[danielyanghansen]

Backend checks if user is part of responsible group when delegating authorization to view allergies.

The corresponding serializer has also been updated to include the "ResponsibleGroup" field so that frontend also can check if user should be able to see the allergy tab
