Front end validation decision/implementation

[aarongundel]

Are we using front end validation with vue? If yes, what does that look like?

Some thoughts:

• the primevue input components take some props like invalid that we could set if required
• knowledge of required nodes, widget labels, default values, placeholders etc could be gotten from OPTIONS request to serializer
• we could show per-field errors from the serializer in line with the form fields instead of just all together in the error toast (error toast currently just says "Bad Request" but the network tab shows the per-field errors the frontend could consume
