feat(messenger): attachments in chat — upload, send, and render

CrmMessagingAdapter now implements upload() (presign-upload → PUT → presign-download
→ Attachment with contentRef), so the composer's attach button appears; send()
forwards the attachment to the socket; and incoming messages (history + realtime)
resolve a presigned display URL. Pull SDK 0.1.4.
