Consolidate Qml Modules Some

[HTRamsey]

Closes #13172
We don't need all these individual modules. They just add complexity

[Copilot]

Pull Request Overview

This PR simplifies QML module usage by removing individual QGroundControl submodules (Palette, ScreenTools, Templates, etc.) and consolidating them under the QGroundControl and QGroundControl.Controls URIs.

• Unified QML imports to import QGroundControl and import QGroundControl.Controls, removing all import QGroundControl.Palette, import QGroundControl.ScreenTools, and related module imports.
• Updated QGroundControlQmlGlobal to register all QML types under the consolidated QGroundControl URI and removed the legacy hasMAVLinkInspector property.
• Cleaned up CMake files to remove the ScreenToolsModule and adjust QML module registrations accordingly.
• Updated documentation to reflect the new import patterns.

• Removing the hasMAVLinkInspector Q_PROPERTY may break QML references expecting this property. Verify and update all QML code that accesses QGroundControl.hasMAVLinkInspector or remove those references.

    Q_PROPERTY(bool     hasAPMSupport           READ hasAPMSupport              CONSTANT)

src/QmlControls/QGroundControlQmlGlobal.cc:83

• The URI for FactValueGrid was changed from QGroundControl.Templates to QGroundControl. Ensure that any QML files importing the old module have been updated to import QGroundControl 1.0 so they can resolve the new URI.

    qmlRegisterUncreatableType<FactValueGrid>           ("QGroundControl",                       1, 0, "FactValueGrid",       "Reference only");
