fix: restore style for pad.ws logo in auth modal (#98)

* fix: restore telemetry in App.tsx

* style: update AuthDialog.scss for improved modal background and backdrop effects

- Added a semi-transparent background color and blur effect to the modal backdrop for enhanced visual appeal.
- Overrode the Excalidraw already overriden background styles to ensure consistent appearance across the application.
