 * @brief Shared address-book contact picker popup.
 *
 * Header-only so Send (and later Chat "new conversation") can reuse it without
 * pulling the address book into the material layer. Trigger with
 * ImGui::OpenPopup(id) from a button, then call this every frame. On selection
 * it copies the chosen contact's address into outBuf (NUL-terminated) and
 * returns true.
 *
 * @param id      Popup id (must match the ImGui::OpenPopup(id) call).
 * @param book    The App-owned address book (app->addressBook()).
 * @param outBuf  Destination buffer for the chosen address.
 * @param outSz   Size of outBuf.
 * @return true on the frame a contact is picked.
