Unable to Enable/Disable Plugins in Self-Hosted Huly Platform

### Issue Description:

The self-hosted version of Huly lacks essential functionality to enable or disable plugins through the plugin management interface. This limitation is affecting our ability to effectively utilize and manage plugins. Specifically, we are unable to enable the Leads plugin, and its availability on the hosted platform is inconsistent, appearing and disappearing at times.

### Steps to Reproduce:

1. Install the self-hosted version of Huly.
2. Observe that there are no options or controls available for managing plugins. (from ui or in options)

### Expected Behavior:

The plugin management interface in the self-hosted version of Huly should provide options to enable or disable plugins, allowing users to customize their deployment according to their needs.

### Additional Information:

- Huly version: 0.6.221 and 0.6.238

We appreciate the efforts put into developing and maintaining the Huly platform. Enabling plugin management functionality in the self-hosted version would greatly enhance the platform's flexibility and usability for users.

Thank you for your attention to this matter.

Best regards,
Gaurav
