**Add type hints and Google‑style docstrings for public CLI command functions and helpers.**

`list_speech_models_cmd` and `register_audio_commands` lack type hints and comprehensive docstrings. Per coding guidelines, all public functions must include Google-style docstrings with Args, Returns, Cost, and Example sections, plus type hints for all parameters and return values. This pattern is also absent across other CLI command files (`imaging.py`, `click_app.py`).

In `@packages/core/ai_content_pipeline/ai_content_pipeline/cli/commands/audio.py`
around lines 46 - 56, The functions list_speech_models_cmd and
register_audio_commands are missing type hints and Google-style docstrings;
update list_speech_models_cmd to include a return type of None and add a
Google-style docstring with Args (none), Returns (None), Cost, and Example
sections, and update register_audio_commands to accept a typed parameter (e.g.,
group: click.core.Group or click.Group) and return None, also adding a
Google-style docstring documenting Args (group), Returns (None), Cost, and
Example; ensure the docstrings follow the same format used elsewhere (Args,
Returns, Cost, Example) and apply the same pattern to other public CLI functions
if present.
