Do not set a disallowedAreaForEndBounds in proto1 window decors

The disallowedAreaForEndBounds is meant to be used when another
component will handle a drag move end in that region (such as a
transition to fullscreen in desktop mode proto 2) and the positioner
does not need to finalize the bounds change with a WCT.
Proto 1 window decorations do not have another component handling
the task-moves within the status bar region, so the disallowed
area should not be set so that the positioner can finalize the bounds
correctly.

Bug: 281761492
Test: drag-move a task in freeform in proto1 into the status bar
area, release and confirm the task surface or caption is not stuck
behind the status bar.
