deal with () in filenames by escaping them (NO_JIRA)

[jasonccole]

This change should 'escape' file names when calling subprocess commands so that they dont fall down on linux platforms (as is currently happening in this PR) for filenames containing certain characters:

See: https://github.com/ccdc-confidential/cpp-apps-main/actions/runs/13816850366/job/38652179948?pr=4142

I'd appreciate a careful check - seems to work on my machine, but I've no easy way to test it in the 'live' repo.

Ironically the PR fails in checks ... because of the python version :-}

Update: PR now works since I've changed the python version in the PR. Horribly self-referential!

Update 2: following a chat with Simon & Matt - I've changed it so that we instead use subprocess without Shell=True - this should resolve the syntactic issues with files

A few f-strings no longer needed. Otherwise should be fine.
