Add type hints to cli.__init__.py

[hnet158158]

What this PR does / why we need it:
Adds type hints (annotations) for all variables and the main() function signature in cli.__init__.py, improving code clarity and enabling stricter mypy checks.

Changes:

• Added from __future__ import annotations for forward-compatibility
• Annotated parser, subparsers, all subcommand parsers (p_pull, p_list, p_dash, p_run, p_auth, p_grid, auth_subparsers, p_login, p_status, p_logout) with argparse.ArgumentParser
• Annotated args with argparse.Namespace in main()
• Added return type -> None and parameter type argv: list[str] | None = None to main()

Closes #190

Thx for your work! Please, resolve merge conflict, and I will merge this PR

[hnet158158]

Merge conflict resolved. The AUTH section was dropped (since it was removed upstream) while keeping RUN + type hints and the new GRID section from upstream.

@hnet158158, thx!

We don't need run, please remove it as well. Also, kindly check why tests are failing
