fix: taskiq admin middleware doesn't work with python <3.11

[danfimov]

Fixes

Import from datetime import UTC is valid only with python version equal or higher 3.11 - docs.

Also type hint with str | None not working in python versions lower than 3.10, because PEP-604 was implemented in python 3.10.

So I fixed an import + type hint and added some basic tests to just calling code from this files and make sure that it works. I also added ruff rule FA102 to prevent this issues in future commits.

Mics

Update anyio version in poetry.lock to enable anyio_mode=auto in tests and get rid of pytest.mark.anyio decorators. They added this ability in last version - release notes (see 4.11.0)

Pull Request Overview

This pull request upgrades the anyio dependency from version 3.x to 4.x and removes the @pytest.mark.anyio decorators from test files. The upgrade allows pytest-anyio to automatically detect and run async tests through the new anyio_mode = "auto" configuration in pyproject.toml. Additionally, the PR replaces the deprecated datetime.UTC with timezone.utc for Python 3.9+ compatibility.

Key changes:

• Upgraded anyio from >=3 to >=4 (version 4.11.0 in lock file)
• Added anyio_mode = "auto" to pytest configuration to enable automatic async test detection
• Removed @pytest.mark.anyio decorators from all test files (decorator no longer needed with auto mode)
• Changed datetime.UTC to timezone.utc in the middleware for broader Python compatibility
