--- Fix Finnhub market caps stored in millions instead of absolute USD.
---
--- Context:
---   Finnhub profile2.marketCapitalization is in millions of USD.
---   Pre-fix rows stored that value as-is (e.g. SPCX ~1.8e6 → "1.8M micro").
---   Correct absolute USD is value * 1_000_000 (e.g. ~1.8e12 → "1.8T mega").
---
--- Identification:
---   Chained fundamentals write source provenance into unavailable_fields_json:
---     "source_market_cap": "finnhub"
---   FMP / Alpha Vantage rows are already absolute USD — leave them alone.
---
--- Safety:
---   After a successful update we stamp market_cap_unit = "usd" so this script
---   is idempotent (safe to re-run).
---
--- Database: PostgreSQL (production).
--- Run against your app DB, e.g.:
---   psql "$DATABASE_URL" -f scripts/fix_finnhub_market_cap.sql
--- or step through the sections in a SQL client.
