fix(ci): install pytestarch in docling-compat workflow

The daily docling-compat job manually installed only pytest, pytest-asyncio
and httpx, which made test_architecture.py fail with ModuleNotFoundError:
no module named 'pytestarch' — wrongly opening 'Docling compatibility break'
issues. Align with ci.yml by installing requirements-test.txt instead.
