Current evaluation

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.

Issue body

`charmcraft upload-resource` fails to upload a local OCI image if the OCI image has a tag (e.g. `charmcraft upload-resource test-application-167531 mysql-image --image dataplatformoci/mysql-and-shell:latest`) I believe this happens because the check for a digest (e.g. `dataplatformoci/mysql-and-shell@sha256:599fe5e5073102dbb0ee3dbb65f049dab44fa9fc251f6835c9990f8fb196a72b`) checks if `:` is in the string instead of checking `@`
