feat: add fleet status page with bulk actions and camera fly-to

- Add POST /api/nodes/{mac}/reboot endpoint for node reboot
- Add POST /api/nodes/update-all endpoint for OTA update all nodes
- Add POST /api/nodes/rebaseline-all endpoint for re-baseline all links
- Add GET /api/export endpoint for configuration export
- Add POST /api/import endpoint for configuration import
- Add SendRebootToMAC and GetConnectedMACs to NodeIdentifier interface
- Frontend already has full table view with:
  - Sorting and filtering by role/status
  - Search by MAC or name
  - Bulk selection with checkboxes
  - Position column with fly-to links
  - Individual action buttons (flyto, identify, diagnostics)
  - Bulk action buttons (identify selected, restart selected, update all, re-baseline all, export, import)
  - Diagnostics modal
  - Statistics footer
