Get Wolt's curated homepage restaurant/store collections for a location

Returns Wolt's own curated homepage restaurant/store lists for a location (e.g. top-rated, newest, hot-this-week -- whichever collections Wolt's own ops team currently curates for that market), read from Wolt's anonymous homepage endpoint. Each restaurant carries the same fields /wolt/search returns. The response also carries is_serviceable, which says whether Wolt delivers to the requested coordinates at all: false means the coordinates are outside Wolt's delivery coverage, so the empty collections list is a coverage answer rather than a served location whose homepage happens to carry no curated lists.
