The keyboard-aware repositioning of dialogs was too aggressive and broken. Removes the CSS rule, dialog-keyboard-aware class, and global keyboard detector mount. The useKeyboardVisible hook is preserved for ArticleEditor.

* Detects whether the virtual keyboard is likely open on mobile devices.

* Uses the Visual Viewport API to compare the visible viewport height against
|
|
* the full layout viewport. When the keyboard slides up, `visualViewport.height`
|
|
* shrinks while `window.innerHeight` stays the same (or changes minimally).
|
|
*
|
|
* A threshold of 0.75 (75%) is used — if the visible area is less than 75% of
|
|
* the layout viewport, we assume the keyboard is open.
