Fix keyFiltersOperation not persisted in dashboard configuration

filters-dialog.component.ts was the bridge between filter-dialog
(which sets keyFiltersOperation on the Filter object) and the
dashboard configuration JSON. It was dropping the field in three
places:
- createFilterFormControl: form group had no keyFiltersOperation field
- edit path: patched filter/editable/keyFilters but not operation
- save(): rebuilt Filter objects without keyFiltersOperation
