fix(docker): copy migrations directory and alembic.ini into Docker image

The Docker container failed to start because the Alembic migrations
directory was not being copied into the image. The init_db() function
calls _run_alembic_upgrade() which requires /app/migrations to exist.

Added COPY instructions for ./migrations and ./alembic.ini to both
Dockerfile and Dockerfile.local.
