manage.py only found the database via BACKUP_DASH_DB, which is set in
the systemd unit and not in an admin's shell, so it silently created a
new backup-dashboard.db in the current directory. API keys created
there were never seen by the service.
- Settings now come from /etc/backup-dashboard/backup-dashboard.env,
which both the systemd unit (EnvironmentFile=) and manage.py read;
real environment variables still take precedence
- manage.py prints the database it uses and refuses to create a new
one unless --create is passed; --db overrides the path
