Hand off render view to mini capsule immediately on player collapse

The capsule's claim on the shared render view is declined during the
player window's fade-out (the window is still visible, so the steal
guard refuses), and nothing retried after orderOut - the capsule stayed
black until the render watchdog recovered the view ~10 seconds later.

Call recoverSharedPlayerViewIfNeeded() in hide()'s cleanup right after
ordering the window out, so the view moves to the capsule as soon as
the collapse finishes. The PiP path is untouched - there the view must
stay in the hidden window.
