Fix pytest asyncio deprecation warning

[James Chapman (JC-wk)]

Resolves #4778

Summary

This PR fixes a pytest-asyncio deprecation warning by explicitly configuring the asyncio mode and default event loop scope for test fixtures.

Details

when pytest --ignore e2e_tests is ran from the root (as documented) Pytest emits a PytestDeprecationWarning indicating that the configuration option
asyncio_default_fixture_loop_scope is unset. With newer versions of
pytest-asyncio (>= 1.3.0), this will become an error unless explicitly configured.

PytestDeprecationWarning: The configuration option "asyncio_default_fixture_loop_scope" is unset.
The event loop scope for asynchronous fixtures will default to the fixture caching scope. Future versions of pytest-asyncio will default the loop scope for asynchronous fixtures to function scope. Set the default fixture loop scope explicitly in order to avoid unexpected behavior in the future. Valid fixture loop scopes are: "function", "class", "module", "package", "session"

How is this addressed

• Sets asyncio_default_fixture_loop_scope = function in pyproject.toml
• Updates async fixtures and test markers to be compatible with strict mode
• Ensures async client fixtures properly manage lifecycle using async context managers

All tests pass locally under pytest-asyncio >= 1.24.0.
