feat(payload-handler): wire MoveTooltip (E6 completes PayloadHandler)

E6 closes out the PayloadHandler resurrection. MoveTooltip handles the cross-viewport AddonLifecycle tooltip-repositioning logic — reads MainWindow.LastViewport/LastWindowPos/LastWindowSize (from A1) to filter events and reposition the native item tooltip away from the chat window. Whole method marked `public unsafe void` per spec §4.2 (matches v1.5.6 exactly — avoids per-read unsafe-block scoping). LogWarning added on the unexpected-AddonArgs early-out branch (wires _logger into real use, prevents CS0414 unused-field warning). PayloadHandler is now feature-complete. F registers it in DI; G wires the AddonLifecycle.RegisterListener for MoveTooltip from a HostedService; H adds MessageList.AttachPayloadHandler setter-injection.
