Draw-queue race: ProcessQueue processes the world-map and minimap queues
independently. When a frame was unloaded while still queued, its
minimap-queue entry could trigger the deferred Unload first (removing
both icons and clearing _needsUnload), then a later map-queue entry
re-added the world-map icon -- orphaned, since Unload had nil'd the
questIdFrames/_G reference, so it lingered until /reload while the
minimap cleared. Unload now drops the frame's pending draw-queue entries
(new QuestieMap:DequeueFrameDrawCalls) so an unloaded frame can never be
re-added to a map.
