fix(anim): Phase L.1c seed move-to locomotion

Browse source 
Retail MoveToManager::BeginMoveForward calls MovementParameters::get_command (0x0052AA00) and then _DoMotion/adjust_motion, so a server-controlled MoveTo begins visible forward locomotion before the next UpdatePosition echo. Seed RunForward for MoveTo packets that omit ForwardCommand, while preserving active locomotion and letting position velocity refine walk/run/stop.
