feat: landing page, schedule action, editorial calendar LLM, Fase D foundations

Landing Page:
- Public landing page at /landing with hero, features grid, CTA
- ProtectedRoute redirects to /landing instead of /login when not auth'd
- Editorial Fresh design: Fraunces headings, clamp() responsive sizing

Schedule Action:
- "Schedula" button appears after approving a post
- ScheduleModal: date/time picker, creates ScheduledPost via API
- Reminder to connect social accounts for automatic publishing

Editorial Calendar LLM:
- Backend: generate-calendar now calls LLM to generate hook + brief for each slot
- Uses character profile (voice, target, niche) for contextual ideas
- Respects brief strategico from the UI
- Frontend: slots show AI-generated hook (Fraunces serif) + brief description
- Each slot has "Genera contenuto →" link for one-click content generation
