handling of OSF requests via OSF redirect service

[jadeddelta]

this PR continues on the COS grant work, now adding support for users on the OSF website to access DataPipe via a custom pop-up window. this will handle both the linking of accounts (without a nodeIri, just userIri) and creating experiments that are automatically tied to a specific component, as opposed to the regular workflow of assigning a component via getting the id themselves.

things to work on before merge:

• [ ] finish up linking setup make sure it all works
• [x] update .env files to properly use osf staging links
• [ ] automatically pick location based on the location of the parent component
• [x] add notification to user if we are not in the production environment
• [ ] make sure that when an account is deleted, the database entry of them is also deleted
