fix(sql): opportunity_score income ceiling /200→/35000 (economic power)

PPS values are 18k–37k but /200 normalisation caused LEAST(1.0, 115)=1.0
for ALL countries — 20pts flat uplift, zero differentiation.

Fix: /35000 creates real country spread:
  LU 20.0pts, DE 15.2pts, ES 12.8pts, GB 10.5pts (vs 20.0 everywhere before)

Default for missing data 100→15000 (developing-market assumption, ~0.43).
Header comment updated to document v2 formula behaviour.
