feat: add proxyImageById endpoint for detail page images

GET /api/v1/heritage-image/image/{imageId} fetches a single image by
its own PK, allowing the detail page to proxy each image in the
images[] array independently.

- /heritage-image/{siteId}        → primary image (list page)
- /heritage-image/image/{imageId} → individual image by PK (detail page)
