kpdev 252cc19f93 Infer Content-Type for document image endpoint (#15368 )

## Summary

Fixes [#15367](https://github.com/infiniflow/ragflow/issues/15367) —
`GET /api/v1/documents/images/<image_id>` always returned `Content-Type:
image/JPEG` even for PNG/WebP chunk images and extensioned thumbnails.

## Related Issue

Fixes #15367

## Change Type

- [x] Bug fix
- [x] Regression tests
- [ ] New feature
- [ ] Refactor

## What Changed

- Added `_detect_image_content_type_from_bytes()` —
PNG/JPEG/GIF/WebP/BMP magic-byte detection
- Added `_content_type_for_document_image()` — object-key extension via
`CONTENT_TYPE_MAP`, then magic bytes, else `application/octet-stream`
- **`get_document_image()`** — set inferred `Content-Type` instead of
hardcoded `image/JPEG`
- Also guards missing storage blob (`Image not found.`) to avoid
`make_response(None)` (same handler; complements #15365)

## Files Changed

| File | Change |
|------|--------|
| `api/apps/restful_apis/document_api.py` | MIME inference helpers +
handler update |
|
`test/testcases/test_web_api/test_document_app/test_document_metadata.py`
| 3 unit tests |

## Validation

```bash
cd /root/gittensor/ragflow
pytest test/testcases/test_web_api/test_document_app/test_document_metadata.py::TestDocumentMetadataUnit::test_get_document_image_content_type_from_object_extension_unit -v
pytest test/testcases/test_web_api/test_document_app/test_document_metadata.py::TestDocumentMetadataUnit::test_get_document_image_content_type_from_magic_bytes_unit -v
pytest test/testcases/test_web_api/test_document_app/test_document_metadata.py::TestDocumentMetadataUnit::test_get_document_image_missing_blob_unit -v
```

## Test Plan

- [x] `.png` object key → `image/png`
- [x] Extensionless chunk key + PNG bytes → `image/png` (magic bytes)
- [x] Missing blob → 4xx `"Image not found."`
- [ ] CI green
