PLA-1181 fix silent image rejection

ApiCall resulted in action being not authorized which in turn resulted in image being

Instead of ignoring invalid images move them to questionable state.

which seem like a much better option :)
fix typo
remove early and unneeded status change.

as final step task already sets status to APPROVED
use const where appropriate
