Title: [WIP] Return validation errors via the REST API

Enable a structured validation error response (422) that returns
each validation error. Normalize the field value for validation
errors so that it corresponds to the real JSON value (rather than
the internal value). Use the same constants in api/types.go and
api/errors/errors.go for validation errors.
