Jack Levy 8911351c99 fix: DB password — read from secrets file, bypasses Docker Compose interpolation
- Add secrets/db_password file support to docker-compose.yml (Docker secrets mount)
- config.py reads POSTGRES_PASSWORD_FILE if set, builds DATABASE_URL with proper URL encoding
- Remove inline DATABASE_URL construction from docker-compose.yml (was subject to $VAR interpolation)
- Any password with any characters now works — no escaping needed
