fix: replace ping-based wait with apt-get/ip route checks, bootstrap curl before installer

- ping not available in base Debian 12 LXC — was silently hitting 20s timeout
- curl may also be missing — install it explicitly before running lxc-install.sh
- use ip route check for network readiness instead of ping
