CI improvement: First check syntax & always display error/audit logs

[marcstern]

First check syntax, in case no error.log is generated. this displays error on console.
Always show error.log (in sub-menu) after start. Even if error and CI processing stops. Same for audit log (even if empty for the moment)

Replaces #3172

Thanks @theseion for the review - @marcstern I think the suggestions (for using grep command) are useful. I'm not sure anyone will check Github logs after a CI run, so if the workflow shows there is any error in the log, that might be much helpfully.

@theseion - thanks for your help again.

Could you take a review again and resolve conversation where it's possible?

[theseion]

Two small changes. @marcstern please resolve the comments. Unfortunately, as owner of the review I can't resolve them myself.

It looks like my review doesn't count towards the merge check. Not sure why.
