feat(data-tables): live register edits, help link, test-dialog table API

Shared-memory register edits now mark the project modified the moment the
user types, test dialogs see uncommitted register values, frame parser and
output scripts can read project-wide constants, and the Shared Memory
toolbars expose a Help entry mirroring the frame parser view.

refactor: replace QtWebEngine with QtWebView for lighter footprint

Use the platform-native WebView instead of the full Chromium-based
WebEngineView. Key adaptations: load HTML via loadHtml() since WebView
does not support qrc: URLs, and use document.title for JS-to-QML
signaling since onNavigationRequested is unavailable.
