Chore: add generic type parameters to remaining serializer classes

Parameterize ModelSerializer subclasses in paperless/serialisers.py
(UserSerializer, GroupSerializer, SocialAccountSerializer,
ProfileSerializer, ApplicationConfigurationSerializer) and
AccountField (PrimaryKeyRelatedField[MailAccount]) in
paperless_mail/serialisers.py.

Regenerate baselines: mypy [type-arg] count 137 -> 131.
