Most of the API annotations are directly converted. The changes in meaning are:
- Parameters "in body" is not supported anymore. These are changed to "in query" or to a request body (depending on the code).
- Add missing translations
- Add some tests
- Add `/api/taggingrule/export` API endpoint
- Add baggy theme
- Add error message when importing tagging rules failed
- Also fix all translations (I think we are good now)
