fix(hero): the albedo renders - two blockers, both at the map level

The generated ashlar albedo never showed for two reasons that had nothing to do with the material graph,
which was verified correct the whole time (TextureSampleParameter2D -> Multiply -> Base Color, colour sampler,
texture set, 6x UV tiling):

1. **The map overrode every hero slot.** The generic per-slot material pass in ue_build_demo_map.py assigned
   the facade KIT's flat stone to every actor whose slot names looked like stone, banner, glass - including
   Hero_Facade. Whatever the import authored was replaced at map build time. The hero is now excluded and gets
   its own materials.
2. **Mesh slot assignment does not persist.** Assigning to mesh.get_editor_property('static_materials') returns a
   copy; after a reload the mesh still pointed at the original imported materials (measured twice). Component
   level overrides do persist in the saved map, so apply_hero_materials() sets them in both builders.

The elevation now renders as coursed, grainy warm limestone with banners, window bays and recessed portals.

Rows 4-6 re-rendered and pending review; the comparison plate is regenerated. Still missing against the
reference: carved inscription, medallion relief, banner lettering, crimson banner tone. The two-model judge
returns no/no (0.90/0.95) - it wants the text and detail that are still absent, which is at least the right
complaint this time.

-- [ ] **Make the generated ashlar albedo render.** It is imported to `/Game/Hollywood/Textures/T_FacadeAshlar_AI`, the material contains `TextureSampleParameter2D` -> `Multiply` -> Base Color with 6x UV tiling, and the mesh has UVs - but the elevation still shows the flat tint. Probe the compiled Base Color pin, and whether `TextureSampleParameter2D` needs its sampler type set explicitly.
+- [x] **Make the generated ashlar albedo render.** Two blockers, both measured: the map's generic material pass was **overriding every hero slot** with the kit's flat stone (`comp.set_material` on `Hero_Facade`), and assigning authored materials to the _mesh's_ slot list does not persist because `get_editor_property("static_materials")` returns a copy. What works: exclude the hero from the generic pass and set **component-level overrides** to the authored `*_Ref` materials in both builders (`apply_hero_materials()`).
