Add Docker support to smoke test, add inject-wifi.sh

Smoke test improvements:
- Add --docker flag for testing Docker containers
- Skip SSH/systemd checks in Docker mode
- Docker health check verifies HTTP response
- Show "Docker Smoke Test" header in Docker mode

inject-wifi.sh:
- Add to repo (was gitignored)
- Add cleanup trap for robustness
- Supports NetworkManager (Bookworm) and wpa_supplicant (legacy)
