[HT-573]

Running a silent install, the DESKTOP_SHORTCUT property is ignored and a desktop shortcut is always created. For example when passing DESKTOP_SHORTCUT="" (msiexec /i app.msi /qn DESKTOP_SHORTCUT="") a shortcut is created anyway.

DesktopShortcutFeature previously defaulted to Level="1" and relied on dialog <Publish> events to disable the feature. Since silent installations (/qn) bypass the InstallUISequence, those dialog events do not run and the feature remains at Level="1".

This change

• Sets the baseline for DesktopShortcutFeature to Level="0"
• Adds <Level Condition="DESKTOP_SHORTCUT = &quot;1&quot; OR UILevel &gt;= 5" Value="1" /> so the feature is enabled in silent installs only when DESKTOP_SHORTCUT="1", while remaining enabled at the start of interactive installs so they work as before.

Testing

Tested using a packaged test MSI configured with create_desktop_shortcut = true:

• Silent install with DESKTOP_SHORTCUT="" (msiexec /i app.msi /qn DESKTOP_SHORTCUT=""),
• Silent install with default settings (msiexec /i app.msi /qn),
• Interactive GUI install with "Create a desktop shortcut" unchecked,
• Interactive GUI install with "Create a desktop shortcut" checked.

Note: This is also the case in beeware/briefcase-windows-app-template. If you feel that these changes are reasonable I'm happy to open a matching PR there.
