Fixed Incorrect "No Interfaces" Display in Plugin Editor

[mdwigley]

Description

This change corrects the property bindings in SettingsPluginsView.axaml that previously referenced HasNoInterfaces.
The correct property is HasNoDescriptors, which properly reflects whether a plugin has any descriptors defined.
By updating the bindings, the "No Interfaces" message is now only shown when appropriate, preventing misleading UI states.

Motivation and Context

The bug caused the "No Interfaces" box to appear for all plugins, even those with valid interfaces.
This fix ensures the UI accurately reflects plugin state, improving clarity and preventing user confusion.

How Has This Been Tested?

• Verified in the plugin editor that plugins with valid interfaces now correctly display their interface table.
• Confirmed that the "No Interfaces" message only appears when a plugin truly has no descriptors.
• Tested across multiple plugins to ensure consistent behavior.
