+PresenceLeave — Sends a Discord webhook when the targeted host LEAVES the network.
+- Triggered by the scheduler ONLY on transition ON->OFF (b_trigger="on_leave").
+- Targeting via b_requires (e.g. {"any":[{"mac_is":"AA:BB:..."}]}).
+- The action does not query anything: it only notifies when called.
