Fix clipped top controls and stale top padding in corner fullscreen

The fullscreen video layer extends up into the status bar strip and is
shifted with an offset; `.clipped()` came after the offset, so it clipped
to the unshifted frame and cut the top strip (title row, avatar) off. Clip
before the offset instead.

The player controls read the main window's safe area only on geometry
changes. With the corner layout keeping its geometry fixed across the
status bar hide, the value went stale and the controls kept the status bar
height as top padding in fullscreen. Refresh it when the status bar
visibility changes, with a few delayed re-reads to cover the fade.
