fix(integrations): restore _clear/_update_init_options public imports

The refactor that split integration commands moved
_clear_init_options_for_integration and _update_init_options_for_integration
into integrations/_helpers.py, but tests still import them from the top-level
specify_cli package, causing ImportError. Re-export them with explicit aliases
at the end of __init__.py to preserve the public import surface.
