Fix progress output in non-interactive shells

[aryasalem09]

Description

Adds automatic TTY detection to the ParticleSet.execute progress bar.

Passing disable=None to tqdm preserves the progress bar in interactive terminals while suppressing it when stdout is redirected to a non-interactive environment, such as a Slurm job log.

The added regression test verifies both interactive and non-interactive stdout behavior without depending on exact progress-bar formatting.

Hi @aryasalem09, thanks for the PR! I'm not 100% sure if this PR is something that we're willing to accept though. A significant workflow of our users is to monitor SLURM log files and disabling the progressbar for not TTY shells will hide this output and make things confusing for users.

This is unfortunately a low-priority issue with also no real clear solution :/
