fix(mobile): normalize keyboard height device-px -> points (was overshooting ~3x on 3x screens)

Browse Source 
Root cause: the Keyboard plugin reports keyboardHeight in device pixels on this build; CSS needs points,
so the raw value overshot by the devicePixelRatio. Divide by DPR when the raw value exceeds the screen's
point height. Web-only.
Build marker -> 2026-07-18-batch102.
