## Summary
<!-- Provide a brief summary of the changes you have made and most
importantly what they aim to achieve -->

Introduce keyboard handling for WKWebView: add WebViewKeyboardAvoidance
helpers for animation metrics and overlap calculation, a WKWebView
extension to run a JS command that scrolls the focused editable element
into view, and a managed bottom constraint for web views so the view is
animated above the keyboard. Wire up keyboard observers and
DispatchWorkItem scheduling/cleanup in WebViewController and
OnboardingAuthLoginViewController, and add the
scrollFocusedElementIntoView JavaScript to WebViewJavascriptCommands.
Add unit tests verifying the bottom constraint creation and JS contents.
