fix: page editor — share dropdown, pill toolbar, link copy

Share panel: dropdown under Share button (not modal), with Private status,
Copy link, Publish toggle, Invite section — matches Notion design.

Get Started toolbar: at bottom with pill-shaped buttons (border-radius:9999px),
shows Ask AI, AI meeting note, Database, Form, Templates, … (Table/Board/List/
Timeline/Calendar/Gallery/Import).

Link copy button (🔗): uses navigator.clipboard, shows '✓ Copied' feedback.

Removed old modal overlay CSS, replaced with .share-dropdown + .gs-pill styles.
