[FEATURE] Added a feature to lock the portfolio created

[Darkoo04]

🚀 Feature description

Is there a way to generate a read-only version of the portfolio? I would like to share a link with a client where they can see the result without having access to the editing tools.

💡 Problem/Motivation

It would be great to have a ‘Lock’ feature or a ‘Read-only’ mode. This would allow us to share the portfolio with potential clients without the risk of the layout being changed.

📋 Proposed solution

Create a button with an admin password so that only the portfolio owner can modify it.

🔄 Alternatives considered

• Generate a link for the client to access it.
• Create a button for the admin password.
