ifcviewer: move volume readout helpers into ViewportCore (#84-j)

Browse Source 
Tiny followup to #84-i — move the const-lookup volume helpers used by
bonsai's measurement HUD:

  double volumeOfObjects(const std::vector<uint32_t>&) const
  vector<pair<uint32_t, double>> volumesPerObject(
                              const std::vector<uint32_t>&) const

The det3OfPlacement static helper moves with them into ViewportCore.cpp's
anonymous namespace (the original kept its mirror in
ViewportWindow.cpp; ViewportWindow's own internal callers are gone now
since these methods moved).

Pure read of models_gpu_ + mesh_local_volumes — all in core already.
Trivial transplant.

Builds: desktop / bonsai / web all green. Tests 100/100.
