Fix workflow tab for recordings

[snoesberger]

During processing and after the publication of a recording, the event details tab does not show any information about running or completed workflows. With this PR the workflow tab shows again all workflow information for recordings, just as it does for manually uploaded videos.

podman run --rm -it -p 127.0.0.1:3000:3000 ghcr.io/opencast/opencast-admin-interface:pr-1475

Specify a different backend like stable.opencast.org:

podman run --rm -it -p 127.0.0.1:3000:3000 -e PROXY_TARGET=https://stable.opencast.org ghcr.io/opencast/opencast-admin-interface:pr-1475

It may take a few seconds for the interface to spin up.
It will then be available at http://127.0.0.1:3000.
For more options you can pass on to the proxy, take a look at the README.md.
