**Add type hints and Google‑style docstring; remove unused `ctx` and `@click.pass_context` decorator.**

The `ctx` parameter is unused (Ruff ARG001) and the `@click.pass_context` decorator serves no purpose without it. The public CLI command handler must include type hints for all parameters and a complete Google-style docstring with Args, Returns, Cost, and Example sections per coding guidelines.

[warning] 22-22: Unused function argument: `ctx`

```
In
`@packages/core/ai_content_pipeline/ai_content_pipeline/cli/commands/imaging.py`
around lines 21 - 23, The generate_grid_cmd function currently accepts an unused
ctx parameter and is decorated with `@click.pass_context`; remove the ctx
parameter from the signature and drop the `@click.pass_context` decorator to fix
ARG001; add full type hints for all remaining parameters (prompt_file: str,
grid: int, style: str, model: str, upscale: bool, output_dir: str, save_json:
bool and return type -> None) and replace the short docstring with a
Google-style docstring that documents Args, Returns, Cost, and an Example usage
for the CLI command so it matches project guidelines.
