fix: resolve residual image files issue after document deletion (#7964)
### What problem does this PR solve?

When deleting knowledge base documents in RAGFlow, the current process
only removes the block texts in Elasticsearch and the original files in
MinIO, but it leaves behind many binary images and thumbnails generated
during chunking. This pull request improves the deletion process by
querying the block information in Elasticsearch to ensure a more
thorough and complete cleanup.
