Merge branch 'feat/receiver-ui' of http://git.dd:3000/AppStd/EnvelopeGenerator into feat/receiver-ui

Refactored mouse event handling in pdfInterop.js to use a new getPos helper, ensuring accurate coordinate mapping on scaled or resized canvases. Updated start and move functions to use this helper. Added an empty settings.json file.
