- database.py: remove dead pre-definition of DATABASE_URL with undefined db_user/db_pass variables - models.py: add missing Table import from sqlalchemy - alembic/env.py: replace deprecated run_async() with asyncio.run() (removed in SQLAlchemy 2.0) - alembic 001_initial: use raw SQL for CREATE TYPE instead of op.create_enum() which requires alembic_postgresql_enum Migration 001_initial successfully applied to trading_data DB.
