Fix player controls clipping in resizable iPad windows

When playing video fullscreen in a resizable window on iPad, the player
height was being forced to UIScreen.main.bounds.size.height, which is
the full screen size. In resizable windows, this caused the player
container to extend beyond the visible window bounds, clipping controls
at the bottom.

Now on iPad, the player uses natural geometry provided by its container
which respects actual window bounds, while iPhone continues using
screen-based calculation for proper fullscreen behavior.
