// Scenario (SCN-dm-open-conversation):
//   Given the DM contact list is rendered,
//   When the user clicks a conversation (onSelectConversation → controller
//     delegate → ProfileDirectMessageActions.handleDmConversationSelect),
//   Then it focuses that conversation and re-renders the thread WITHOUT throwing
//     — i.e. it must call controller/main-controller methods on the right
//     receiver, not on the Actions instance (the bug that made opening any
//     conversation throw "… is not a function" — KNOWN_BUGS #0 follow-up).
