Related to T7334: Kleopatra: ADSK shown as "unknown recipient"

In the decryption results Kleopatra gives a list of recipients.
Like in this screenshot with lots of ADSKs from https://dev.gnupg.org/T7334#207077:

It would be helpful to add the long keyID as given by gpg for the recipients in the Kleopatra output as a way to match the lines of those outputs. This would also help to identify which is the "unknown recipient".

I'm not sure if we should just add it to the information in parentheses. I would prefer to drop some of the current info, which is:

• certified/not certified/not VS-compliant/…
• OpenPGP/SMIME
• created: DATE

From these I find the date to be the most relevant and protocol info the least (as this is the same for all recipients anyway).
