Mixin to handle profile_picture serialization for WebSocket compatibility.

This mixin adds a SerializerMethodField for profile_picture that converts ImageFieldFile objects to URL strings, making them JSON serializable for WebSocket consumers.

The mixin intelligently handles profile pictures from IAMUserDetail by:

1. Accessing the related details queryset on the IAMUser model
2. Extracting the ImageFieldFile from the first detail record
3. Converting it to a URL string for JSON serialization

Usage:

1
class MyUserSerializer(ProfilePictureMixin, serializers.ModelSerializer):
2
    class Meta:
3
        model = User
4
        fields = ['id', 'username', 'profile_picture', ...]

Note:

• This mixin expects the model to have a details related manager
• The related detail should have a profile_picture ImageField
• Returns None if no profile picture is found or an error occurs
