Inconsistent QML module versions across the codebase

We identified inconsistent module versions in QML files (QtQuick, QtQuick.Controls, QtQuick.Layouts, org.kde.kirigami). This issue is to track their standardization in the repository. \n\nReferences:\n- Pull Request: https://github.com/OpenVoiceOS/ovos-gui/pull/70\n- Comment: https://github.com/OpenVoiceOS/ovos-gui/pull/70#discussion_r1898138474\n\n@JarbasAl

💡 Codebase verification

Inconsistent module versions detected across QML files

The codebase shows varying versions for the same Qt modules across different files:

• QtQuick: varies between 2.4, 2.9, and 2.12
• QtQuick.Controls: varies between 2.0 and 2.12
• QtQuick.Layouts: varies between 1.4 and 1.12
• org.kde.kirigami: varies between 2.4, 2.10, and 2.11

Specific files with newer versions that could guide standardization:

• SYSTEM_Loading.qml, SYSTEM_Status.qml, FeatureRequest.qml: Using QtQuick 2.12, QtQuick.Controls 2.12
• RequestHandler.qml: Using QtQuick.Layouts 1.12
• SYSTEM_UrlFrame.qml: Using Kirigami 2.11

Consider updating all QML files to use these newer, consistent versions to ensure compatibility and maintainability.
