Dashboard & Profile Page - Improvemens

[app-generator]

We need to improve the private section of the project by using some pages from the PRO version:

• Main Dashboard Page - passive page for now
• User Profile page - passive page for now

Once the user passes the authentication, he is redirected to the dashboard.

Besides the dashboard & profile page, the Sidebar items need to have a PRO pill, and the link will redirect the user to an external link.

The PRO link is read from the env with the default value (if not present in ENV):

@topstar210 please proceed with this.

TY!
