feat: weekly config backup + unified telemetry schema + fleet dashboard
- scripts/backup-config.sh: weekly router config backup to hub (SRM + OpenWrt) Runs via cron, exports platform-specific config, POSTs to /api/backup Keeps last 10 backups per device on hub - hub/ingest.sh: fleet hub telemetry normalizer + backup receiver Normalises GL (openwrt) and Synology telemetry into single schema Adds platform field to GL telemetry for unified dashboard - hub/dashboard.html: single-pane fleet console Shows all routers (GL + Synology) with scores, WAN state, GPS, uptime Auto-refreshes every 10s from /api/status endpoint - 62-point checklist updated with weekly backup section 9b Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
