Always sort asc first for new column

[Arnei]

When sorting by a different column than before (e.g. by title instead of date), the sorting will now always be ascending first. Then on subsequent clicks on the same column you get descending and none. The goal for this patchis to improve the user experience through more intuitive behaviour.

How to test this

Can be tested as is. You can sort a table by a specific column by clicking on the column head.

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/admin-interface:pr-1583

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/admin-interface:pr-1583

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.
