Resolve "Application create modal mistakenly submits on click when job is still running"

The airtable import modal instantly closes the second you click import atm. This is because it's embedded inside another form, and has always had this bug, its just before a hidden validation failing was preventing it from submitting, now with a default name for the application it now submits the form and creates a second database whenever you click. In this MR I completely separate the two forms so one isn't nested inside the other to fix the issue.

How to test

1. Try to import a database from Airtable on develop.
2. See that a blank "untitled database" is immediately made + the import modal closes immediately
3. Checkout this MR
4. Now you should be able to import from airtable without the modal closing
5. You should also be able to create modals normally.
