Initial setup/signup proceeds even if an invalid password is provided

[egasimus]

Issue Summary

Confusing and disorienting behavior during initial setup: did it store the admin password or not?

Steps to Reproduce

1. Start up a blank instance and you're greeted with the admin signup page.
2. Enter a very long password
3. You get an error message that the password must be <60 characters...
4. ...but you're also sent to the next step, initial instance setup.

Technical details

I ain't pasting any server logs until this entire category of bug is resolved lol. Browser console log? Sure:

...and it also contains the entered password in plaintext 🤦‍♂️

Also that button alignment - srsly...

This issue is not fixed. I can still create an account with an invalid password (over 60 characters), and the only indication I'm given that there's any problem is, after I verify my email, when I go to log in, the website hangs.

There should be an indication during sign up that there is a character limit for the password, and the UI should not allow users to but more than 60 characters into that input field.
