Section marks and drawing-view borders are now real acadrust entity
types instead of Unknown-with-extras, so the renderer dispatches on the
variant directly, the arrow-direction resolver reads the active viewport
off the ViewBorder entity, and selection / properties show "Section
Symbol" and "View Border" instead of "Unknown". View borders are
non-plotting and tessellate to nothing; both count toward the lossy
Save-As warning since they round-trip via their raw records.
Bumps acadrust for the entity promotion.

Lights, camera views and the geographic-location marker had no on-screen
representation. Add display glyphs for all three:
- Lights render through a new EntityType::Light: a cone/flashlight for spot
lights, a wire sphere for point lights, a sun for distant lights, sized in
screen space (fixed-world fallback).
- Camera views (perspective VIEW records) and the GEODATA "daisy" marker are
synthesized into the model-space resident wire set from the document, since
they are not entities.

The paper layout sheet pass reused the full model mesh set, so every
top-level 3D solid piled onto the paper origin — the sheet camera works
in paper coordinates, not model space. Guard `meshes` on
`inst.paper_sheet` the same way wires/hatches/images already are: the
sheet shows only paper-native content; the model's solids render inside
the floating content viewports (model camera + per-viewport scissor).
Also name 3DSOLID/REGION/BODY/SURFACE/MESH/SOLID/MULTILEADER in dxf_name
(they fell through to "ENTITY"), and add a SELHANDLES diagnostic that
reports the active space plus a per-type / per-block selection breakdown.

Pull in this session's acadrust work — the HELIX / ACAD_TABLE read+write,
underlay reader/writer/definition, spline tolerances & tangents, etc. The new
EntityType::Helix variant breaks three exhaustive matches; add its arm to
entity_type_name, the UI-name / DXF-name maps and entity_type_key.

ACAD_SURFACE entities now load and render. Their NURBS faces are
tessellated by building a truck BSplineSurface from the ACIS `spline-surface`
control net and knot vectors, then sampling its parametric grid — reusing the
same NURBS kernel the Model tab already builds on. Analytic faces
(plane/cone/sphere/torus) continue through the existing tessellator.
- New spline_tess.rs: parse the ACIS `nubs` block (degrees, knots with the
clamped end-multiplicity fix, control grid) into a truck BSplineSurface and
mesh it.
- tessellate_surface + Surface wired through the mesh-build, fallback-wire,
and entity-classification paths.
- Bump acadrust to the commit that adds the Surface entity.

Two near-identical match-on-EntityType tables lived far apart:
scene/properties.rs::entity_type_name returned mixed-case UI labels;
app/commands.rs::entity_type_name returned uppercase DXF record names.
Both enumerated ~30 variants; adding a new entity meant remembering to
touch two files in two crates' worth of source layout.
Move both into a single entities/names.rs as `ui_name()` and
`dxf_name()`. Adjacent so a new variant gets both labels added at once;
function names make the intended audience explicit at the callsite.
scene/properties.rs and app/commands.rs each lose their local match
plus one re-export, gaining a `crate::entities::names::*` call.
