[BE-SEC-006] security: Implement comprehensive password strength validation
- Enhanced PasswordValidator with additional security checks: * Maximum length validation (128 characters) * Common password detection (password, 123456, qwerty, etc.) * Repetitive pattern detection (aaaa, 1111, etc.) * Sequential pattern detection (1234, abcd, qwerty, etc.) - Added ValidatePasswordChange method to ensure new password is sufficiently different from old password (similarity check) - Updated PasswordService to use enhanced validator consistently - Replaced utils.ValidatePasswordStrength with validators.PasswordValidator - All password operations now use the same comprehensive validation rules Phase: PHASE-4 Priority: P1 Progress: 8/267 (3.0%)
