SetupWizard: Fix import facility superuser password

[nucleogenesis]

Summary

In UserCredentialsForm we were just emitting a submit event with no data, which I found meant that of the internals of SelectSuperAdminAccountForm were thought to be doing some things they weren't w/ the password data.

Also fixes some refs to the password textbox.

Weirdness Note

• I spent a while trying to figure out why the page refreshes when the password is invalid but couldn't work it out. I don't think this is a bug that needs to be fixed here, but I can make a follow-up

Fixes #13103

Reviewer guidance

You must import from a device that has multiiple facilities on it. The reported bug does not replicate unless the device you import from has multiple facilities

1

• Import a facility via the Full device import flow in Setup
• After import, see that when you put a password in for the admin you used to authorize the import, there are no errors and you are redirected as expect.

2

• Import a facility the same way again
• After import, see that you can successfully create a new superuser

3

• Regression test On My Own flow
