Route account region from channel reaction tag message

Account records fall out of sync when regional picks stay only in channel reactions, delaying handoffs. This keeps the account's engineer region current and enables follow-up within minutes.

Overview

When reps mark a message with a region reaction, the account should reflect that choice in the CRM instantly. This flow converts those channel signals into an Account picklist update and a threaded confirmation, reducing manual edits and ensuring correct routing within minutes.
