Input for all screens

" summary

As more large-screen devices appear, apps need concrete input support: updating to Jetpack Compose 1.2 alpha 2 enables click and scroll for mouse/trackpad; testing reveals 85% use peripherals more than half the time. Implement OnKeyListener or onPreviewKey to handle Enter/Escape and dispatchKeyShortcutEvent for Ctrl shortcuts; set nextFocusForward/focusProperties and clear unnecessary focusable views; add hover via OnHoverListener or clickable/hoverable; interpret action cancel for stylus and consider the low latency stylus library for drawing performance.
