- Added 4 missing columns to _ensure_translation_jobs_columns() inline migration: target_language_column, target_source_column, target_source_language_column, disable_reasoning — these were in the SQLAlchemy model but had no Alembic migration or _ensure_*() coverage - Added missing api_key, assistant, clean_release model imports to alembic/env.py so autogenerate can see all tables
Generic single-database configuration.
