fix: database-image.yml never installed workspace members or ran migrations

Discovered opening PR #2: this workflow only triggers on pull_request (and
push to main), so it never ran against this branch until the PR was
opened -- meaning this bug was pre-existing and unrelated to today's new
tests. uv run pytest implicitly syncs, but not with --all-packages, so
starter_core/reflex/reflex_local_auth were never installed; even
pre-existing tests/test_auth.py and tests/test_vertical_slice.py failed
collection here, not just the new auth/bootstrap tests.

Added uv sync --all-packages (matching ci.yml) and uv run alembic upgrade
head (the app-level tables test_vertical_slice.py and the new auth tests
need don't exist without it -- this workflow never ran migrations).

Verified locally against a truly fresh container (docker compose down -v,
rebuild, up) running the exact new step sequence: 12/12 database or
integration tests pass.
