**Add type hints and Google-style docstring; remove unused `ctx` parameter.**

The `ctx` parameter from `@click.pass_context` is never used in the function body. The function is missing type hints for parameters and return value, and the docstring must include Args, Returns, Cost, and Example sections per coding guidelines.

```
In `@packages/core/ai_content_pipeline/ai_content_pipeline/cli/commands/audio.py`
around lines 24 - 27, Remove the unused click context and add type hints and a
Google-style docstring to transcribe_cmd: delete the `@click.pass_context`
decorator and the unused ctx parameter from the function signature, annotate all
parameters (e.g., input_path: str, output_dir: str, language: Optional[str],
diarize: bool, tag_events: bool, keyterms: Optional[List[str]], save_json: bool,
raw_json: bool, srt: bool, srt_max_words: int, srt_max_duration: float) and the
return type -> None, and replace the short docstring with a Google-style
docstring that includes Args, Returns, Cost, and Example sections describing
each parameter and behavior; keep function name transcribe_cmd unchanged so
callers match.
```
