Add main-menu Rotation for webview-only page turns (#136)
* Add main-menu Rotation for webview-only page turns.

Cycle 0/90/180/270 from the History menu without rotating system or chrome;
swap document width/height so pages reflow like a landscape layout, then map
onto the portrait nest (Chromium ignores View scale, and nest LayoutParams blank tabs).

* Make webview Rotation reliable on physical devices.

Drive CSS from the active tab WebView with Java-side CSS pixel sizes,
retries, and a post-apply verify — visualViewport-only sizing and a
nest search were enough on the emulator but could silently no-op on
real WebView/density setups.
