fix(config/scripts): Enhance User Creation and Ban Handling, Standardize Imports (#1144)

* chore: use relative imports for scripts

* fix(create-user): newUser.save() now properly awaited, double-check user creation, use relative imports, catch exception

* fix(ban-user): catch exception, handle case where IP is undefined, proper check of user ban on login
