feat: save claim attachments to cloud storage and documents page

- Claim file uploads (chatbot or manual) now save to both the Cloud
  Storage patient folder and the Documents page via new
  POST /api/claims/upload-to-cloud endpoint
- MH submit flow now calls uploadAttachmentsToLocalFolder (same as
  DDMA/United/Tufts) so chatbot-attached X-rays are persisted
- Removed old /upload-attachments disk route and attachmentDiskStorage
  multer config; deleted uploads/patients/ folder
- uploadAttachmentsToLocalFolder now points to /upload-to-cloud and
  sends patientId so the backend can create the patient folder
