The user may want more control over how many pixels per beam there are in the final image. This is probably more important for point-source science, and the fact that the ALMA pipeline aims for 5, while we aim for 3. Visually, there's a significant step up in visual fidelity going from 3 to 5 pixels per beam, but we currently have no control over that in postprocessing.

Summary

Exposes the min_pixperbeam parameter used when compressing cubes, so it can be set from the loop_postprocess call:

• loop_postprocess gains min_pixperbeam: int = 3, passed to recipe_cleanup_one_target in the cleanup step.
• recipe_cleanup_one_target and task_compress gain the same typed argument, replacing the hardcoded min_pixperbeam=3 passed to trim_cube for both the casa and spectralcube methods.
• Each function documents the argument in Google docstring style.
• Default is unchanged (3), so existing behaviour is preserved.
• CHANGELOG entry added.

Testing

• With CASA/analysisUtils stubbed and trim_cube mocked, loop_postprocess(do_cleanup=True, min_pixperbeam=5) passes 5 to trim_cube for both casa and spectralcube, and 3 when omitted. On master the same call raises unexpected keyword argument 'min_pixperbeam'.
• ruff reports the same 4 pre-existing warnings as master.
• The full CASA test suite was not run locally.
