Remove the redirect.py file
Split the one controller into three

- __init__ has the main endpoints where no login is necessary
- elections has the elections related endpoints (voting, results...)
- admin has the administration related endpoints (create, edit, delete...)
Give a warning information message to admins seeing an embargoed election

And format a little the warning messages (as orange)
Make the runserver.py file executable
Remove import of the redirect file since the file no longer exists
