Fix crash on printer switch from stale filament/extruder indices (#14103)

Browse Source 
Switching to a printer with fewer filaments (e.g. H2D -> X2D) threw
std::out_of_range in check_filament_printable. Clear stale per-volume
extruder config on count shrink and bound-check filament indices at the
read sites.
