test(core): WLAN measured with Java FILIUS — a wireless cable is a cable, an SSID connects nothing

WlanRun pings on the new network wlan-lan: over wireless cables, over a plain cable, and to and from a notebook on the switch's SSID without a cable. The engine matches Java without a change: it runs the links only. Swift's wirelessAssociations, which join a host to its SSID's switch at run time, are not taken. ScenarioNetwork sets wireless cables, wireless cards and SSIDs; a corpus test pings over the wireless cables of multicast_server.fls. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

+// Runs wlan-lan's network in Java FILIUS (ScenarioNetwork) and records what a
+// wireless connection does at run time: every frame each card saw and when
+// each call started and ended.
+//
+//   WlanRun <scenario.json> <story> <milliseconds> <out.json>
+//
+// Notebooks 192.168.1.11 and .12 with wireless cards on the switch's SSID
+// "schule", each joined by a wireless cable; PC 192.168.1.13 on a plain
+// cable; notebook 192.168.1.14 with a wireless card on "schule" but no cable
+// (as after the switch's SSID changed: Java's editor removes the cable and
+// does not lay it again). The stories:
+//   pingWired          .11 pings .13
+//   pingWireless       .11 pings .12
+//   pingWithoutCable   .11 pings .14
