fix: prevent touchscreen right-click context menu

Modified notification view delegate to check for touchscreen
device type before showing context menu on right-click. Added
PointerDevice.TouchScreen type check to both TapHandler instances in
the DelegateChooser.

The previous implementation would trigger context menu on right-click
gestures from touchscreen devices, which was unintended behavior.
Touchscreen right-clicks are typically long-press gestures that should
not open the same context menu as mouse right-clicks. This change
ensures context menus only appear when using mouse input devices.

Influence:
1. Test right-click with mouse on notification items - context menu
should appear
2. Test long-press/touch gestures on touchscreen devices - context menu
should not appear
3. Verify regular left-click functionality remains unchanged
4. Test touchscreen interactions with other gestures to ensure no
regression
