feat(home): overhaul home screen with bottom nav and UX improvements

- Add persistent bottom navigation bar (Home / Activity / AI / Menu)
- Fix TodaySummary bug: last-log times now show today's events only
- Replace 6 hardcoded AI chips with 3 AI-generated context-aware chips
- Show child's real profile photo in baby card (fallback to 👶 emoji)
- Recent Activity limited to 3 items with "See all →" link to /activity
- "Suggested now" promoted to prominent amber banner with "Log it →" CTA
- Offline pending banner is now a tappable retry button
- Branded loading state with bouncing emoji (🍼 😴 🚼 👶)
- Remove unused Button import from page.tsx
- Expose image_url via /api/children and Child type/FamilyProvider
