Better navigation for ChildrenCountDashboard

[TheSlimvReal]

Describe the bug
When clicking on one of the groupings in the ChildrenCountDashboard you are forwarded to the children overview and the children should be filtered based on the grouping that was clicked on.
Currently this is done by transforming the name of the grouping to lowercase.
This is not always correct and especially with configurable enums this should use the id of the enum instead.

Additional context
In the ChildrenCountDashboard the routing is done like this:

goToChildrenList(filterString: string) {
  const params = {};
  params[this.groupBy] = filterString.toLocaleLowerCase();

  const path = "/" + Child.ENTITY_TYPE.toLowerCase();
  this.router.navigate([path], { queryParams: params });
}

the filterString.toLowerCase is an assumption that is not always correct. Especially when this.groupBy is a configurable-enum property, the id of that enum should be used.
