scripts: стемп-бэкфилл для прода + e2e /analyze (login form-urlencoded)

- prod-stamp-backfill.sql: бэкфилл search_models v1 из cases.analysis_log
  (для БД, где таблицы 006 уже созданы create_all — стемп alembic_version).
- e2e-analyze.sh: живая проверка /analyze на CT108 (bike 8yo 2h лес день
  -> max_distance 5.4; login — form-urlencoded, не JSON).
- Мелочь: test-mig-seed.sql ON CONFLICT DO NOTHING.
