F form helpers

Summary

For https://gitlab.indiscale.com/caosdb/customers/umg/management/-/issues/72. Create API functions to make HTML elements for form modals with which SSS are triggered.

Focus

Just copied existing code from customer projects to form_elements.js. Also use the new functions in ext_trigger_crawler.js.

Test Environment

Make sure that the unit test for ext_trigger_crawler.js still passes.

For manual testing, use, e.g., the caosdb-ekfs profile in local-s3-button. Make sure that the crawler forms still work as before.
