Replace deprecated [Rpc(..., RequireOwnership = true)] with InvokePermission = RpcInvokePermission.Owner on the owner-submitted draft/buff RPCs (PlayerDraft, PlayerBuffManager), matching the pattern already used elsewhere. Also commits the .meta files Unity generated for the new sell-VFX scripts so their GUIDs are stable across machines.
