PolyfaceMesh and PolygonMesh were wireframe-only. They now render with
the same flat-color solid fill as Face3D entities.
- Add fill_tris: Vec<[f32;3]> to TruckEntity and WireModel
- PolyfaceMesh: fan-triangulate each face into fill_tris
- PolygonMesh: triangulate each grid quad into fill_tris
- tessellate.rs Lines branch: apply world_offset to fill_tris
- Face3DGpu::from_wires: collect fill_tris from all wires in addition
to Face3D key_vertices quads
- upload_face3d: pass all_wires so fill_tris are batched into one draw call
Three root causes caused all geometry and UCS arrows to disappear:
1. TruckObject::Lines and TruckObject::Text variants returned world-space
f32 coordinates without applying world_offset, so fit_all() computed
bounds spanning from local space to UTM world space (~4 M m), placing
the camera impossibly far from all visible geometry.
2. Ray/XLine entities with unnormalized direction vectors (common in some
DXF exporters) produced astronomically large far-point coordinates
(up to 1e28) that overwhelmed the camera fit even after the offset fix.
Fixed by normalizing the direction vector before multiplying by
DISPLAY_EXTENT.
3. Origin-stuck corrupted entities (coordinates ≈ 0 in world space become
≈ -world_offset in local space) pulled the fit_all() bounds far from
the actual drawing. Fixed by computing local_extent_max from EXTMIN/EXTMAX
(10× safety margin) and skipping points outside that range in fit_all().
Additional hardening: wire_gpu.rs now skips ±inf segments (not just NaN),
and snap_pts/key_vertices in all TruckObject variants are offset-corrected.

- polyline.rs: TruckConvertible/Grippable/PropertyEditable/Transformable
for all three polyline types; Polyline2D handles bulge arcs via the
same truck Wire path as LwPolyline; Polyline and Polyline3D use
TruckObject::Lines for straight-segment rendering
- ray.rs: Ray renders as base→+1e6; XLine renders as ±1e6; both have
base-point and direction grips; mirror correctly reflects direction
vector; base X/Y/Z and Dir X/Y/Z exposed in properties panel
- traits.rs: dispatch all five new entity types through
to_truck_entity, grips, geometry_properties, apply_geom_prop,
apply_grip, apply_transform
