fix(calls): the call PiP no longer opens on top of the composer (#323)

The first-use PiP position was bottom-right, 72px from the bottom: on
desktop over Send, on phones over Send, Emoji and the message box, so
the first thing you typed or tapped in the text room hit the call.
Default to top-right under the room header instead. A dragged position
is still remembered.
