feat: phase A — backup B2, healthcheck /api/status, vector tiles Tippecanoe
- A1: scripts/backup-postgres.sh — pg_dump quotidien compressé → Backblaze B2 (rclone), rétention 30j - A2: StatusController retourne HTTP 503 + healthy/alertReason si dernière observation > 6h - A4: Dockerfile installe tippecanoe, GenerateTilesCommand génère 5 tilesets (obs + h6/12/24/48), Caddyfile sert /tiles/* sans fallback SPA, SargassesMap.jsx passe en sources vector tiles statiques - chore: backend/public/assets/ ajouté au .gitignore (build artifacts) - chore: setup vitest frontend + ImpactScoreServiceTest (session précédente) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
