Add password strength requirements during registration and password reset

[evadecker]

We should implement password requirements to reduce the risk of phishing and account loss.

For email validation haveibeenpwned suggested by the docs offers a limited free plan .

I found mailchecker which doesn't do the same job as haveibeenpwned but rather validates if the email is not a temporary/spam mail which can be a start(still checking the package).

What do you think?

@belhajManel I love the idea of implementing some email validation using mailchecker or haveibeenpwned but let's save that for another PR.

For this PR, it would be great to implement https://zxcvbn-ts.github.io/zxcvbn/ for password-checking.

We'd want to:

1. Create a new PasswordStrength component to display the strength of a password from 0-4 (a segmented bar with a label and color, something like this)

2. Display the new component beneath the password input for registration

3. Initialize the zxcvbn-ts library and hook up the password strength to the component

4. Display warnings and suggestions returned from the library in a banner to help the user pick a stronger password (example API response)

5. Prevent registration if the password is too insecure (maybe scores below 3?)
