[Enhancement]: Add passwordrules to sign-up

Checked Existing

• [X] I have checked the repository for duplicate issues.

What enhancement would you like to see?

Sometimes, users' password managers might generate passwords that will get rejected by the server because they use disallowed characters. This is annoying UX.

Any other details to share? (OPTIONAL)

Is this a dupe of #164, or an extension of it? #164 only mentions Apple, but it is about password rules.

If this issue is meant to supersede #164 then we should close it.

288 is also likely relevant here, though I never got a response back for what characters were causing issues. More research needs to be done on that.

1Password and potentially other password managers (unsure which ones) use the Apple standard previously mentioned there.
