sExport should make usage of ProductListService, etc instead of own queries

[mitelg]

the product data in sExport is queried by a big SQL. this should be replaced with the ProductServices we have

Evaluate if this could be done in a bugfix release, otherwise we need to do it in 5.8

I think, this is not possible or you have an idea how to make the "sql custom filters" possible with the ProductService. :-)

[mitelg]

you have a point here 😁

This was just a simple idea back then. Made without the knowledge of each and every possibility of the feature 😉

Maybe it could be done, if this feature is skipped and custom conditions could be added with a plugin 🤷
