feat: offline mode — drop binaries in /opt/fw/offline/

Offline deployment for air-gapped corporate environments:
- /opt/fw/offline/docker-29.2.1.tgz → Docker static binary
- /opt/fw/offline/wallarm-node.tar → Wallarm Docker image
- Setup auto-detects and uses offline files
- Falls back to apt/docker.io if no offline files
