Clean up default pnd uuid in toml files

Description

There are different parameters for default PND UUID's in the example config toml files.

basepnduuid and pnduuid

This might need some investigation but definitely needs to be cleaned up, e.g. remove the one that is not in use or adjust parts of the code in case both of these parameters are used somehow. Since there is no example toml file for CLI, during the changes it would also be a good idea to add one while working on this particular issue.
