Adds full circle functionality — private social groups for trusted families
to share milestones, memories, and posts with reactions and comments.
- 7-table DB migration: circles, members, invites, posts, comments, reactions, reports
- 11 API routes: create/list circles, posts feed, comments, emoji reactions, invite tokens, join flow, member management, reporting
- 3 new pages: /circle (list), /circle/[id] (feed + PostCard + CreatePostModal), /circle/join/[token]
- Copy-on-share for memory photos (independent R2 objects, never references originals)
- Admin controls: invite generation, member promote/demote/remove, last-admin guard
- C9 privacy consent screen before first post
- Menu entry added
