Add Password Strength Bar in Signup Form

[duplixx]

Bug Description:
The signup form currently lacks a password strength bar, making it challenging for users to assess the strength of their chosen passwords during registration.

To Reproduce:

1. Navigate to the signup page.
2. Enter a password without a strength indicator.
3. Observe the absence of a password strength bar.

Expected behavior:
A password strength bar should be implemented in the signup form to visually represent the strength of the entered password, providing users with feedback on the security of their chosen passwords.

Actual behavior:
The signup form does not feature a password strength bar, leaving users unaware of the strength of their passwords during the registration process.

@duplixx We already have validation for the password fields, adding a bar is not required.
