Feat: viewport UCS name picker from document UCS table

Browse source 
- properties.rs: inject 'UCS Name' Choice property for viewports when
  document.ucss is non-empty; resolves current handle to display name
- update.rs: intercept PropGeomChoiceChanged for 'vp_ucs_name'; clones
  UCS origin/x_axis/y_axis into viewport and sets ucs_handle — no
  trait signature change required
