Issue body
Trying to upload an oci-image resource from dockerhub to charmhub for my charm fails if I specify the image digest but is working when giving the image name and tag.
Failing with image digest:
```

| #1051 Fix digest check for uploading OCI resource | charmcraft | closed | Closed after fixing the OCI image upload digest check in charmcraft. The validation logic was corrected to check for @ instead of :, resolving failures when uploading tagged images. | |
| #1953 Charmcraft 3 should still accept image digests for `upload-resource` | charmcraft | open | Charmcraft 3 `upload-resource` rejects bare image digests (e.g. sha256:…) that charmcraft 2 accepted; the ImageService lacks a digest-based lookup via RepoDigests. Unlabeled, no maintainer response, only a bot Jira-sync comment. | |
| #871 Support both image id and digest when uploading oci-image resources (CRAFT-1324). | charmcraft | merged | Merged implementation supporting both image ID and digest for OCI image uploads. ID usage bypasses remote registry checks for faster processing, while improved messaging handles missing images gracefully. Resolves #853. | |
| #906 `charmcraft upload-resource` 2.1.0 removes ability to pass tagged image names to `--image` argument | charmcraft | closed | Closed as solved. Affected teams migrated CI to use image digests instead of tags. Rather than reverting the change, PR #912 was created to improve error messaging when tagged image names are provided. |
