Python: Simplify Python Poe tasks and unify package selectors (#4722)

* updated automation tasks and commands, with alias for the time being

* Restore aggregate test exclusions

Preserve the legacy all-tests scope for test --all by excluding lab and devui from the default aggregate sweep, while still allowing explicit package selection. Also ignore hidden/generated test directories such as .mypy_cache during aggregate discovery.
