Declare Salary | Statistics for wage percents by position

Task #12093 | 5062.000 [5061.100]

Wage submission was adjusted for statistics reporting. So far, wage value of 100% was always exported, even if the person worked part-time. This was implemented and checked as part of the certification. 

Wages for persons with part-time employment will now be submitted based on the calculated percents by position. The billed wage items value is taken into account.
