Require authentication to use REST API, bump year

"fscoli next" is based on the ["Fachschaft Computerlinguistik WordPress Theme"][original], Copyright 2015 personads, which is also distributed under the terms of the GNU General Public License v3.0.

It contains modifications made by Jakob Moser in 2020–2023, namely added responsiveness, a few bug fixes and a rewrite of the underlying HTML, PHP and CSS. Jakob also modified the `screenshot.png` image to include the name of the new theme. The original design work by personads was left more or less intact, so there is little visual difference between the two themes.
