Add password strength validation on signup page

[jvkousthub]

Implement a password strength validation feature that provides visual feedback on password strength through color-based indicators. This enhances the user experience by clearly showing the strength of the entered password.

Character Variety: Passwords must include:
At least one uppercase letter (A-Z)
At least one lowercase letter (a-z)
At least one digit (0-9)
At least one special character (e.g., !@#$%^&*)
Color-Based Indication
Weak (Red): Passwords that do not meet the minimum length or contain only one type of character.
Moderate (Orange): Passwords that meet the minimum length and include at least two types of characters.
Strong (Green): Passwords that meet the minimum length and include all required character types (uppercase, lowercase, digit, special character).
