fix(hero): lift the colonnade into the photographed 50-60% band

Measured from the built mesh, the colonnade (columns + capitals) was 6.90 m of the
14.50 m elevation = 47.6 %: the entablature (3.40 m) and parapet (2.20 m) were
using 5.60 m of the height. Thinned both to 3.00 m and 1.80 m in
hero_facade_build.py, which lifts the colonnade to 7.70 m = 53.1 % - inside the
50-60 % band - with the envelope, motto band and medallions unchanged relative to
the parapet.

Hero rebuilt, re-imported (bounds 2604 x 1257 x 1450 cm), DemoMap rebuilt and the
screenshot set re-rendered for review. Hero part report updated (columns 7.45 ->
8.25 m, entablature 3.40 -> 3.00 m).

TODO: colonnade item closed. MEMORY records the FBX-vs-blend --out gotcha.
