Admin user creation

[Nick Bolles]

Small bug report that I just ran into where if you use a capital letter in the admin username you can't login because everything else lowercases the username (as it should). The fix is to not use capitals in the username or to lowercase it in entrypoint.sh when we create the user.

if ADMIN_USERNAME = Nick

Created in Database as "Nick"

and try to login with "Nick"

the client lowercases it in the response

Confirmed that If I delete the user in the database and change ADMIN_USERNAME to "nick" it works as expected. Whether I enter "Nick" or "nick" as the username on the client
