Pull the phone number out of the listing

Some Carousell sellers paste their WhatsApp number straight into the listing description instead of using the in-app contact button — against policy, and trust & safety wants to find and mask them.

From carousell_listings, return the listing_id and the phone number found in description as phone_found, for every row where an 8-to-11-digit run of digits (allowing for a leading +, spaces, or dashes stripped away) appears. Return just the digits, no punctuation. Order by listing_id.
