Fix: reset BuildVolume belt state when leaving belt mode (R1)

Browse Source 
Non-belt branch of set_bed_shape reset only the 3DBed renderer, not the
BuildVolume; Bed3D::set_shape early-returns on unchanged bed, so a
belt->normal switch or in-place belt toggle-off left the BuildVolume with
m_is_belt_printer=true and inflated Y bounds -> out-of-bounds objects
treated as printable on a normal printer.
