refactor: switch upload to new POST /api/upload with flat FormData

Replace the old nested upload_info JSON approach with flat
multipart fields (typeId, region, fileRole, createdBy, autoRun,
speed) matching the new leaudit-platform backend.

- uploadDocumentToServer: POST ${API_BASE_URL}/api/upload
- handleFileUpload: pass region from userInfo.area, derive speed
  from priority enum, pass createdBy from JWT user_id
- UploadResult replaces FileUploadResponse with documentId/fileId
  replacing the old nested result.id/result.file_name pattern
