Integrate error handling with ConfigData

[Venefilyn]

We need to retrieve error handling when submitting a form, and if possible, retrieve field validation rules for each ConfigData and display them together with the field. Basic structure exists as a error_data field within ConfigData and Config models.

One way would be to utilize Vee-validate and Vee-validate-Laravel and format errors that way. Another would be to utilize Vuelidate but would need a mapping between front-end and back-end validation.
