- Replace hardcoded PD API bearer token in db_calls.py with dotenv/env var
- Delete scripts/supabase_doodling.py (dead scratch file with hardcoded Supabase JWT)
- Add python-dotenv dependency and .env.example template
- Consolidate check_prod_missing_ratings.py to import AUTH_TOKEN from db_calls
- Hard fail if PD_API_TOKEN is missing to prevent silent auth failures
