Disable unnecessary migration job in Helm chart

The application handles database initialization internally via SQLAlchemy's
create_all() method in database.py. The separate migration job was causing
deployment failures and is redundant since the app automatically creates
tables on startup.

This simplifies deployment and eliminates the migration job failure point.
