Add fetch_category_names to Eviivo, QBook and Mews profiles

- Eviivo: no-dates page fetch returns all room types with data-item-name and
  data-rate-plan-name; single request populates the full name catalogue
- QBook: item_name already in /api/pull response; extracted on a dummy date
  call; no distinct rate plan names exposed so rate_labels left empty
- Mews: getCalendarData (bookingEngineId field) returns resourceCategories[].name
  and rates[].name as {en-US: ...} dicts; both room and rate labels populated
