Smart WoL: TCP pre-check before sending magic packet (3s timeout). Machine status updates via SSE: online/offline tracked in DB and broadcast to all connected browser tabs in real-time. - Pre-check: if machine already reachable, skip WoL and mark online - WoL path: send 3 magic packets, wait for SSH, mark online/offline - Backend: setMachineStatus() helper + machine_status SSE event - Frontend: subscribeMachineStatus() SSE helper for Machines + Dashboard - IsReachable() helper in wol package for TCP reachability checks
