Fix video position jump when dismissing the portrait details panel

Two causes: the drag/dismiss animation targeted the content-area center
(screenHeight/2) while the resting position once the panel flips hidden
is fullScreenHeight/2 - top inset - the player window adds extra bottom
safe area, so the two centers differ and the flip snapped the video by
half that difference. And the hidden-state flip ran on a fixed 0.25s
timer that cut the 0.3-response spring short, snapping the video the
rest of the way. A shared hiddenVideoY is now the target everywhere
(drag interpolation, dismiss animation, swipe-up reveal), and the flip
runs in the spring's completion callback.

Also mark DEBUG os_log output public: without it the console shows
<private> for processes not launched by Xcode (e.g. USB syslog capture).
