Reduce duplicate code for modal content

[Arnei]

This code structure appears in like 50 files, so I'm putting it in a component so I don't have to see it again.

While there are many changed lines, 99% of them are indentation changes, so this is hopefully fairly easy to review.

How to test this

Can be tested as usual.

[github-actions]

Use docker or podman to test this pull request locally.

Run test server using develop.opencast.org as backend:

podman run --rm -it -p 127.0.0.1:3000:3000 ghcr.io/opencast/opencast-admin-interface:pr-1059

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-1059

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.

Could you separate the whitespace changes into a separate commit?

[Arnei]

I can try.

[Arnei]

Although the white space changes are directly related to the introduction of the new component, so it seems reasonable to me to have them in the same commit. Can you explain to me how separating them into their own commit helps with git blame?

If the white space changes are directly related to the introduction of the new component then leave them as-is.
