gsxdsm f3732afcd0 FN-5858: fix multipart chat attachment sends ...

Handle multipart chat message requests so uploaded attachments reach the chat manager.

- parse multipart bodies on the chat message SSE endpoint with attachment count and size handling
- persist uploaded message attachments into session storage and forward generated metadata to sendMessage
- add multipart route coverage for successful sends, missing content validation, and the published package changeset
