[FIX] web: fix properties mobile display

Fix the property mobile display:

- Set the popup in fullscreen.
- The draggable feature is disabled.
- Replacing the move up/move down property arrows in the popup by a
back arrow so that the fullscreen popup can be closed.
- Removing the min-width on the property popover to prevent the popup
from going out of the screen.
- Edit button is now always visible as hovering on it is not possible on mobile.
