feat(shell): add share button to global header with QR, copy link, email invite 

Extract canvas inline share panel into reusable <rstack-share-panel> web component
and add it to the shell header between notification bell and settings gear. Canvas
now uses the component too, removing ~230 lines of inline HTML/CSS/JS.
