Implement password strength requirements

[VictrixHominum]

Which feature are you enhancing?
User account security through password policies

Why is this required?
Weak passwords are a common security vulnerability that can lead to account compromises. Implementing password strength requirements will significantly reduce the risk of brute force attacks and credential stuffing, protecting both user data and the platform's reputation.

Any additional context?

1. Define password strength requirements:

   • Minimum length (at least 14 characters)
   • Require combination of uppercase, lowercase, numbers, and special characters
   • Prohibit common passwords and personal information

2. Implement client-side validation:

   • Create password strength validation utility in /src/lib/passwordValidation.ts
   • Add real-time password strength meter component
   • Display specific feedback on which requirements are not met

3. Implement server-side validation:

   • Add validation middleware for registration and password change endpoints
   • Integrate with a common password database (like "Have I Been Pwned")
   • Return clear error messages for failed validation

4. Update user interfaces:

   • Enhance registration form with strength indicators
   • Add password strength visualization to password change forms
   • Include password requirement explanations in the UI

5. Add password history tracking:

   • Create database schema for password history
   • Prevent reuse of previous passwords (last 5)
   • Implement secure comparison for history checks
