Replace duplicated LoadConsentCategoriesByCookieBannerID,
CountConsentCategoriesByCookieBannerID, and
LoadAllConsentCategoriesByCookieBannerID with a single
CookieCategoryFilter in pkg/coredata. The filter uses the
standard CASE WHEN idiom to optionally exclude a kind,
eliminating branching in the service layer.
