Create password.js

This Script Include validates the strength of a password. It can be used in scenarios like:

User self-registration (ensuring strong password before allowing submission).

Custom portal forms (when users create accounts or update passwords).

Service Desk workflows (where support staff reset user accounts and must set secure passwords).
