Improve translation (and original strings)

The wording around 'presenting' AKs and 'reso intention' was ambiguous and diverged in some places. This should unify the terminology across the different modules.

I'm not sure about your policy on autogenerated po file updates — the automated changes are isolated in the earliest commit; you might want to cherry-pick the later commits if you want to exclude the automated changes.

I've also fixed a few minor typos in the translations (in a separate commit).
