Put opening hours, service area and FAQ into the structured data

Settings gain opening hours per weekday and a list of places served;
LocalBusiness emits openingHoursSpecification (equal times grouped) and
areaServed. An accordion can be marked as FAQ (schema v23 property
`faq`), which turns its entries into a FAQPage built from the visible
title and text blocks. Elektro Bernhard gets the real office hours
(Mo–Fr 07:30–17:00), the service area from Karlsruhe to Offenburg and
two more questions. ADR 094.
