Subject: [PATCH] clean up test config after pytest-homeassistant migration

Follow-up to #888:
- remove duplicate --asyncio-mode=auto from addopts (asyncio_mode is
  set in [tool:pytest])
- comment why -p no:respx is needed
- filter two third-party import-time deprecation warnings (Home
  Assistant http server, backoff)
- remove the commented-out pytest block from pyproject.toml
- remove the auto_enable_custom_integrations fixture; the
  pytest-homeassistant hass fixture enables custom integrations by
  default
- document uninstalling pytest-homeassistant-custom-component when
  upgrading a venv to Home Assistant 2026.11+

+If you are upgrading an existing virtual environment to Home Assistant 2026.11 or later, you must
+first uninstall the old `pytest-homeassistant-custom-component` package, which has been replaced by
+`pytest-homeassistant`. Its pytest plugin still loads if it is installed, and it fails with
+Home Assistant 2026.11+:
+```bash
+venv/bin/pip uninstall -y pytest-homeassistant-custom-component
+python -m pip install -r tests/requirements_test.txt
