frontage: south block frontage, plus the placement bug it exposed
Adds the five remaining verified south-side buildings to the demo block (6922, 6902, 6838 El Capitan Theatre, 6822 Budget, 6806-6820, 6800 Lee Drug), exported in place from the OSM blockout by Tools/export_block_frontage.py, imported to /Game/Hollywood/Frontage/ and staged by the demo builder with the look material set (stone for the theatres, stucco for the retail run). Adding neighbours exposed a pre-existing placement bug that was invisible while the hero facade stood alone in an empty field: - UE south is +Y here (south sidewalk Y +718..+1447), but the hero sat at Y -1450 on the NORTH side of the street. - It was also at X -12024..-9420, 26 m east of the 6840 footprint; the frontage gap between 6902 and 6838 is X -14591..-12082. - The two north-side buildings were on the SOUTH side, because their exporter mirrored Y. Fixes: hero moved to X -13336 / Y +1307, inside its frontage gap; the frontage and north-building exporters no longer apply a Y mirror (the FBX preset already lands Blender -Y south on UE +Y south); player start and demo cameras moved to the north sidewalk looking south; sun raised to pitch -62 so both frontages read instead of the north side silhouetting. Result: the demo is a street - continuous south frontage with the hero in it, both sidewalks, the road with the designated crossing, and the north-side buildings across the road. Screenshots re-rendered and approved by the owner. Squash of branch frontage-block-0.1.0 (PR #6).
