Working hours New more columns in overview

Additional columns should be added to the overview of working times in the New working times. In our case it is mainly about which working time is in use, so there should be 2 more columns in the overview, one for "in use by personnel" and one for "in use in projects".
Then you would see immediately whether a working time is still in use at all.
Just like in the role management there is also the column "in use" for the roles.
