feat(render) Campaign FW1: port the exact retail degrade selection

Browse source 
UpdateViewerDistance @0x0050e030 + get_degrade @0x0051e4b0 ported with
live-pinned globals: distance measured to the part SCALED SORT CENTER,
effective = max(0, dist - s_rDegradeDistance [live 100]), level = first
with effective < IdealDist (the live auto_update_deg_mul<=0 arm), else
the last level. WalkBuildingDegradeLevel carries the full authored
bands; the adapter fills sort centers; the replay context measures to
the transformed sort center. Sweep state after the rule: the level-0
building set is now correct; the residual divergence is the per-portal
side/clip gate (my arms punch a near-complement of retail two) - the
sweep driver carries the next instrument in its Skip note.
