Feature Request: Disable Project Selector in Navbar

[flechilla]

Description

The current project selector in the navbar should be disabled. By default, this selector should only display the user's default project. If the user clicks on it, they should be informed that this option is only available for subscriptions of type Agencies and be prompted to upgrade. Additionally, we should clarify on the website that the option to have multiple projects is a nice-to-have feature, not limited to just agencies.

Motivation

Disabling the project selector in the navbar will help streamline the user interface and ensure clarity among users who have access to multiple projects. By disabling this feature, we can simplify the user experience and ensure consistency across different types of subscriptions.

Use Cases

• Use case 1: A user with a basic subscription wants to access their default project. They should be able to do so easily without being distracted or confused by the project selector in the navbar.
• Use case 2: An agency user wants to switch between different projects within their subscription. They should be able to do so by upgrading to an agency subscription and accessing the project selector in the navbar.

We are not showing the project selector now. Let's do this for the 1.0.0 release
