feat(auth): option to disable strong password validation

[siddhantk232]

Add option to disable strong password validation in /-/auth/create-account/.
This can be disabled using the FASTN_DISABLE_STRONG_PASSWORD_CHECK env var:

• true: disable validation
• false (or unset): use zxcvbn to check for weak passwords

Also removes some dbg! calls in set_password.rs.

This is because of Nandhini's comments? I am not yet sure if FifthTry should use this feature. I am okay with this being merged in general.

Nope. I added this as a nice option to not have to come up with strong creative passwords when you're in a development environment. I remember you requesting this feature too

Got it. So this is a development feature. We as a convention add either DANGER_ (if it is a prod variable that you should not set normally) or DEBUG_ (for development/debug variables) as prefix. FASTN_DISABLE_STRONG_PASSWORD_CHECK should be renamed to DEBUG_FASTN_DISABLE_STRONG_PASSWORD_CHECK or something.
