Verticaal centreren foto op desktop, iets meer mobiele witruimte

Door items-start op de grid werd de fotocel niet uitgerekt over de
beide rijen, waardoor de flex-centrering in de fotowrapper geen
effect had en de foto naast de kop bovenaan bleef hangen i.p.v.
gecentreerd naast kop + tekst samen. sm:items-stretch lost dit op.
Foto is daarnaast iets vergroot (h-48/w-48 -> h-56/w-56 op sm), en de
mobiele gap tussen kop/foto/tekst is licht verruimd (gap-6 -> gap-8,
mb-2 -> mb-3).
