The connect_force_port test fails intermittently in CI because the hardcoded server ports (60123/60124) may already be in use by other tests or processes [1]. Fix this by passing port 0 to start_server(), letting the kernel assign a free port dynamically. The actual assigned port is then propagated to the BPF programs by writing it into the .bss map's initial value (via bpf_map__initial_value()) before loading, so the BPF programs use the correct backend port at runtime.
