ci: cram: add WoL packet transmission test

Browse Source 
Add a CRAM test that verifies Wake-on-LAN packet transmission
through the Device.Ethernet.WolL.SendMagicPacket RPC.

Use tcpdump to capture the generated UDP port 9 packet
and validate it in CI.

Verify that a Wake-on-LAN packet is transmitted (broadcast UDP/9)
This test only verifies that the DUT sends a WoL packet; no receiver is required.
$ rm -f "$CRAMTMP/wol.cap"
$ alias R="${CRAM_REMOTE_COMMAND:-}"
Start local capture on testbed PC:
$ sudo tcpdump -p -i "$TESTBED_LAN_INTERFACE" -c 1 -nn -e udp port 9 >"$CRAMTMP/wol.cap" 2>&1 &
$ TCPDUMP_PID="$!"
$ sleep 1
Trigger WoL RPC first try:
$ R "ba-cli 'Device.Ethernet.WoL.SendMagicPacket(MACAddress=\"02:00:00:00:00:01\", Password=\"\")' >/dev/null 2>&1 || true"
$ sleep 1
Retry only if UDP is not yet captured:
$ if ! grep -q 'UDP' "$CRAMTMP/wol.cap" 2>/dev/null; then R "ba-cli 'Device.Ethernet.WoL.SendMagicPacket(MACAddress=\"02:00:00:00:00:01\", Password=\"\")' >/dev/null 2>&1 || true"; fi
$ sleep 1
$ if ! grep -q 'UDP' "$CRAMTMP/wol.cap" 2>/dev/null; then R "ba-cli 'Device.Ethernet.WoL.SendMagicPacket(MACAddress=\"02:00:00:00:00:01\", Password=\"\")' >/dev/null 2>&1 || true"; fi
$ sleep 1
Cleanup capture process if still running:
$ sudo kill -9 "$TCPDUMP_PID" >/dev/null 2>&1 || true
Assert that a UDP packet was sent:
$ grep -m1 'UDP' "$CRAMTMP/wol.cap"
