stack tabs: follow WindowControlsPosition for the close button

The window stack tabs build their own Tab widget rather than using
libcosmic segmented_button, so they kept the close button on the right
even with macOS-style controls enabled.

Order the tab items from the configured position: close first when
Start, last when End, with the container alignment following.
