Expose the existing bee-install script through the web UI:
- platform/install.go: remove USB exclusion, add SizeBytes/MountedParts
fields, add MinInstallBytes()/DiskWarnings() safety checks (size,
mounted partitions, toram+low-RAM warning)
- webui: add GET /api/install/disks, POST /api/install/run,
GET /api/install/stream endpoints
- webui: add Install to Disk page with disk table, warning badges,
device-name confirmation gate, SSE progress terminal, reboot button
