refactor(flask): Replace _request_ctx_stack with g for claims storage

Updated the claims storage mechanism in the Flask integration to use Flask's `g` object instead of `_request_ctx_stack`. This change improves code readability and aligns with Flask's recommended practices for storing request-specific data.

refactor(tests): Update tests to reflect claims storage change

Modified test cases to accommodate the change in claims storage from `_request_ctx_stack` to `g`, ensuring that the tests accurately reflect the new implementation.

chore(tox): Update poetry install commands to include Flask extras

Adjusted the `tox.ini` configuration to install Flask-related dependencies during testing and type checking, ensuring that the environment is correctly set up for Flask integration.
