Migrate DB logic from TS to new Data Processor
This way multiple joins are possible. As multiple joins are possible, TYPO3 can add pages to the query and therefore respect the enable fields. Hidden pages will therefore not be part of the result, fixing inaccurate count for none published pages with assigned categories. Also the TypoScript communicates what should happen.
