chore(sample_project): cleanup manage.py and sample_project/settings.py

The `./manage.py` script still contained a fix that was superseeded by
using `apis-override-select2js` long ago, sow we drop that fix.
Additionaly, we point DJANGO_SETTINGS_MODULE to `sample_project`, which
was still pointing to `apis` which was dropped. And we format the whole
file to look more similar to the default Django generated `manage.py`.

The `sample_project/settings.py` now drops the hardcoded secret key and
regenerates one every execution (or uses one from the environment). We
also removed some unused apps from INSTALLED_APPS and unused entries
from MIDDLEWARE and TEMPLATES.
