Improve error message/diagnosis in add rights statement form

[HaSistrunk]

Is your feature request related to a problem? Please describe.

In the add rights form when adding a new rights statement for an organization, the error message for an invalid field in a hidden part of the form does not help the user identify what the error is to correct it.

If there are validation errors, the form reloads with an alert: "Please correct the error(s) below and try again", but the errors that need to be corrected are not specified or visible.

Describe the solution you'd like

Review the approach to form validation and associated error messages and update to help the user know what the errors are and recover.
