Refresh and complete English translations across the site

Fresh-translate home, CV, contact, and gallery content from the
current Dutch source instead of the drifted/embellished prior English
text (CV in particular had invented details not present in Dutch, and
contact was missing a phone number while listing an opening day the
Dutch page doesn't have). Create English versions for the Gallery page
and 20 werk-in-detail albums that previously had none, translating
titles into English. Media fields (media_order, portret, images) left
untouched everywhere. kijkpotten has no Dutch source, so left as-is.
