Validator for internal studies not loading

[becky-gilbert]

Summary

While helping a researcher debug an experiment JS issue, I noticed that our js-validation.js file isn't loading on either the EFP or jsPsych edit pages. I see a 403 error in the network tab. The result is that the validation fails to run on the edit form submit action (because the jsValidation function is not found). The red text that should appear on form submission (#1308) does not show up, but I think the changes are still saved.
