feat(analytics): Sprint N — dashboards CE + admin

src/lib/analytics.ts (NEW) — 3 queries server-only :
- getMonthlyRevenueSeries({organizationId?, monthsBack=12}) → 12
  buckets « YYYY-MM » avec carbetRevenue + rentalRevenue + total.
  Scope optionnel par org via memberships (Booking) et
  provider.organizationId (RentalBooking).
- getCarbetsOccupancy({organizationId?, monthsBack=3}) → liste triée
  par occupancyPct avec bookedNights/totalNights pour chaque carbet
  PUBLISHED (filtré par memberships si org).
- getAdminGlobalKpis() → users (total + breakdown par rôle),
  carbetsPublished, bookings/rentals 30j, revenue 30j, top 5 carbets
  + top 5 providers par CA 30j.

src/components/analytics/MonthlyRevenueChart.tsx (NEW) — bar chart
SVG simple (pas de lib externe), stack carbet + rental, grid Y, tooltips
via <title>, légende couleurs. Responsive overflow-x-auto.

/espace-ce/analytics/page.tsx (NEW) :
- 3 KPIs (CA 12 mois total / Carbet / Matériel)
- MonthlyRevenueChart scopé par org
- Liste taux d'occupation carbets 3 derniers mois (barres horizontales)
- Lien ajouté depuis le dashboard /espace-ce

/admin/analytics/page.tsx (NEW) :
- 4 KPIs (utilisateurs, carbets publiés, bookings 30j, CA 30j)
- Breakdown users par rôle (barres horizontales + pourcentages)
- Carte « Activité 30j » avec bookings carbet + locations matériel
- MonthlyRevenueChart global
- Top 5 carbets (CA 30j) + Top 5 prestataires rental (CA 30j)
- Sidebar admin gagne entrée « Analytics » sous « Vue d'ensemble »

Pas de nouvelle dépendance npm — graphiques en SVG natif.
