Add new optional "broker contact information" to listing details page

[spmiller2]

MLSes are starting to provide the new "broker contact information" that is required to be displayed in markets that choose to require it.

Item 3 on the Nar 2022 notice

The field is option for the broker to enter a value in, and can contain text, a phone number, or an email, so we cannot format or be rigid about the field contents. Also, it may not be included at all, so display should be "where provided" and is to be included alongside the listing office name and any default phone number for the office.

• display if present
• do not remove or replace Listing Office Name, listing office email or listing office phone if present
• add as a new field, possibly "Broker Contact"

The data is returned on the API when include=compliance is included in the query and is returned on .compliance.attributionContact

some examples of data which have been returned so far.

"Cell: 805-285-2396" (note text + number) "803-665-8772" "california@yourbrokerage.com" null "(608) 935-8382" (note parens)
