Missing server side validation on listType

[adam-collins]

I can only find client side validation on list type. There should be something on the server side as well. https://github.com/AtlasOfLivingAustralia/species-lists/blob/develop/lists-ui/src/listTypes.json

[adam-collins]

Add a service to get this list. It is a mandatory field in list creation so the list should be public.

Also, spatial-hub would benefit from a dynamic list.

[adam-collins]

There are other mandatory fields; licence, region. Maybe this new REST service should bundle all the valid values given that the UI restricts them.

Task

• Server side validation for metadata fields that are limited by the UI.
• REST/graphql service to retrieve these limited values.
