[CSV] Configure account autodetection per profile

Dawid Wrobelrequested to merge
work/csv_detection_per_profile into master

CSV importer had a global option enabling account name autodetection based on the header contents. This, however, should only really be enabled if the CSV file contains actual account name, and therefore configurable per profile.

Also: run clang-format against touched source files.

BUG: 444741
