🔊 Add lens of strat_list_list and rp_dct to engine.log

> I found a couple really good spots where we can add reports for verbose
> logging/debugging, to help quickly figure out these forking issues in
> the future. Check the length of strat_list_list right before this loop:

> you quickly see that `freesurfer-subject-dir` is the only one with
> multiple strats/forks in freesurfer_abcd_preproc, and tracing that
> resource's provenance led me to see that there were two versions of it,
> one from regular `freesurfer_preproc` and the other from
> `freesurfer_abcd_preproc`
