fix: Share panel — General Access dropdown + Publish section

Share panel restructured to match Notion:
- General Access: dropdown with 'Only people invited' / 'Anyone with the link'
- Invite: email + permission selector
- Publish to web: toggle + URL input + Copy link button
- Copy page link at bottom

CSS: .share-access-btn and .share-access-menu for the access dropdown
