// Globale app-instellingen (key/value, gecached). Nu vooral de tenancy-modus.
//
//   tenancy = 'solo'  -> precies één site (de primaire/owner-site)
//   tenancy = 'hub'   -> hoofdsite (bedrijf) + /user/, admin wijst PrutFolio's toe
//
// De cache wordt bij setSetting meteen ververst, dus een toggle in Beheer werkt
// live zonder herstart.
