feat: plan limits, café location, nearby API, Iran map section

• PlanLimits: add MaxMenuCategories (Free→3), MaxMenuItems (Free→30),
  CanAccessCrm and CanAccessStatistics (Pro+ only)
• MenuController: enforce category/item limits before create (403 + PLAN_LIMIT_REACHED)
• Cafe entity + EF migration: Latitude/Longitude (double?, nullable)
• CafeSettingsController: PATCH accepts lat/lng with range validation
• PublicController: GET /api/public/map-markers (marketing SVG map feed)
  and GET /api/public/nearby (Koja nearby-cafés with Haversine sort)
• Dashboard settings: location card with OSM iframe preview + Neshan link
• Website homepage: IranMapSection — stylised SVG silhouette with
  SMIL-animated blinking dots at real café coordinates
