Place
A physical location where classes are held.
Places resolve the
locationId a class returns. Fetch the
list once and key it by _id.
Archived places are not returned. A class that references an archived place will
have a locationId you cannot resolve — fall back to showing no location rather
than treating it as an error.
address is always present as an object, but each of street, city,
postalCode, and country is independently nullable.
Only classes use places. Workshops carry their own
address, and online classes have
locationId: null.
