test(pytest): move pytest fixtures to conftest.py

There are a few benefits for this:

  - All fixtures in one module, so single source of truth.

  - The fixtures are automatically imported and injected by pytest
    so no explicit imports needed for these.

  - Linters won't complain about redefinition of outer scope objects.
