fix(crawler): FlareSolverr persistent sessions + DB data field + scraper schema

- flaresolverr.py: refactor stateless (create_session/destroy_session/get)
  L'ancienne approche warmup→cookies→requests était bloquée par Cloudflare
  (JA3 TLS fingerprinting). Toutes les requêtes passent maintenant via une
  session Chrome persistante FlareSolverr.

- ma_http.py: MASession utilise les sessions FS persistantes. Ajout de
  _extract_json (html.unescape + extraction <pre>) et _build_url.
  Gestion du refresh sur 403/429 avec recréation de session.

- db.py: ajout du champ data JSONB dans upsert_bands INSERT+ON CONFLICT.
  Avant ce fix, l'URL n'était jamais stockée → get_bands_to_enrich retournait
  toujours 0 résultats → enrichissement mort.

- scraper_band.py: schéma band_page aligné sur l'historique DB (lineup
  structuré avec URLs artistes, discography_url, lyrical_themes, location,
  info_raw). Ajout de "Themes" dans _pick pour couvrir les deux variantes
  de clé HTML (MA utilise parfois "Themes", parfois "Lyrical themes").

- 005_fix_checkpoints_and_data.sql: renomme last_additions_check →
  last_created_check (clé morte vs clé utilisée par le code). Backfill
  enriched=true + colonnes top-level (formed_year, themes, status,
  location_text) depuis band_page JSONB pour les 85k bands de l'ancien scraper.
