Remove rstack-space-settings slide-out panel. Enhance the existing tabbed
modal in rstack-space-switcher with add-member (username search + email
invite) and pending email invites (with revoke). Header gear now calls
openSettingsModal() on the space switcher instead of toggling the old panel.

On mobile (<=640px), the header right section was too crowded with icons.
Now hides notification bell, share panel, and settings gear buttons, and
adds equivalent mobile-only items in the identity dropdown menu. Share
uses native navigator.share() when available.

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.
