UI bug with file uploads

[controlaltnerd]

I've encountered an issue with a fresh Authentik instance (v. 2023.10.7) where the file picker button and clear background toggle are missing entirely from the flow editor (see screenshot). I've spun this instance up in Docker via a docker-compose file copied from another machine running a known good instance of Authentik.

I've destroyed the container, wiped all data, and rebuilt from scratch several times, but the issue persists across multiple browsers, computers, and IP addresses. My gut says it's a file permissions issue, but the worker container has root access so that shouldn't be an issue.
