Only fetch phone numbers when needed
Phone numbers fetching require extra API calls, and these are rate-limited. We do not want to fetch and store all the possible phone numbers for all posts.
Two options:
- Either query phone number on demand, from the web UI (similar to what is done on housing websites).
- Or simply make all queries in batch at the end of filtering pass, on remaining flats only.
First option has the additional advantage to offer a natural workaround rate limitation.
