Implement all vendor integrations, WAN graphs, and FortiGate health panel

- Wire up 26 vendor providers: Atlassian Statuspage API, Status.io, Instatus,
  AWS RSS feeds, Apple/Google JSON feeds, M365 Graph API, and synthetic checks
- Add 11 new providers: AWS, Cloudflare, SmartPass, School Dismissal Manager,
  SherpaDesk, Classkick, ClassDojo, Savvas, Study Island, Promethean, RAZ-Kids
- Rename Local Infrastructure → Internet (TCP check to 8.8.8.8:53)
- Add WAN throughput graph section: dual-link canvas graphs (Crown Castle +
  Comcast) polling FortiGate REST API every 30s with 30-min rolling history
- Add FortiGate health card: uptime, CPU %, memory % from FortiOS API
- Add /api/throughput and /api/fortigate-health endpoints
- Add README with setup instructions
