* make black

* fix: fail if .superuser file not found; add `--admin-user` option

* fix: ambiguous use of `logger.debug`

- register_new_ext_routes must not be None
- `logger.debug` was used because it allowed any arguments, but that was a bad idea
- now an explicit empty `_do_nothing(*_)` function is used

* fix: load settings

* doc: updated `--source-repo`

* chore: rename `upgrade` to `update`

* refactor: use `@annotation` for making commands async

* fix: code checks
