fix: use Tauri outerSize API for correct new window dimensions

innerWidth/innerHeight in Tauri don't account for title bar height
and are affected by webview zoom. Add brackets.app.getWindowSize()
that uses Tauri's outerSize()/scaleFactor() to get the true logical
window size, and brackets.app.getZoomFactor() using PhStore.
