BPDM Gate: Confidence Criteria Stats Incorrectly Calculated

### Current Behavior

At the moment the stats showing how many shared records have been checked against official datasources and how many are shared by owners only show the total number of records.

### Expected Behavior

I would like the counts to be correct.

### Steps To Reproduce

1. Share a business partner not as own company data
2. Check the stats and see the count increase

Same for official datasources

1. Share a business partner not in an official datasource (like an additional address)
2. See the count increase again for the additional address

No files, tests, or entry points are named. Reproduce the BPDM Gate confidence-criteria statistics using the two sharing scenarios, then trace how counts distinguish official datasource records from owner-only records; done means each statistic increments only for records in its respective category.
