Move repo from ZSEnext project nature to production database resource
With the ZSEnext project reaching completion, I would like to reflect the change in this repository's nature:
- Change remote URL from https://gitlab.opencode.de/uba-emsit/dev/ZSEnext to https://gitlab.opencode.de/uba-emsit/reporting/CSE
- Make sure to update your local git configs!
- Salvage the last few TODOs from the current main README file and move those into repository issues
- Replace the main README with a "non-project" description of the database and the reason for this repository to exist.
