A sole proprietor 10DLC registration now gives a vertical

POST /api/v1/numbers/{id}/10dlc requires a new vertical on the brand when kind is sole_proprietor — the trade the brand operates in. The carrier registry asks for it on every sole proprietor brand, and the earlier form didn’t collect it.

It is the sole proprietor’s counterpart to a business registration’s businessIndustry, but the two take different values: the registry validates them against separate vocabularies. PROFESSIONAL is a vertical, PROFESSIONAL_SERVICES is an industry, and TRAVEL, MEDIA, TELECOMMUNICATIONS, RELIGION, ONLINE, NOT_FOR_PROFIT, AUTOMOTIVE and BANKING are industries with no vertical at all. Sending an industry code where a vertical belongs is rejected.

A business registration is unchanged and takes no vertical.
