Max 57082d1d42 Enhance document management by adding file ID support and updating related fields
- Introduced `file_id` field in the document model to link documents with their corresponding files in the attachment system.
- Updated `AddFileProcess` to include `file_id` in the response, improving document tracking.
- Modified `GetDocument` function to support the new `file_id` field in document retrieval.
- Removed the unused `ScrollDocuments` endpoint to streamline the API.
- Improved error handling and response structure for document-related operations.
