Include module name in artifact path

[jonathanj-square]

Module artifacts stored in the OCI registry using the following path convention: /ftl/modules/<module-digest> but the desired path is /ftl/modules/<module-name>/<module-digest>. When artefact blobs are uploaded to the controller their names are not included (the artefacts table doesn't make use of them).

The change involves:

• [ ] Including the module name when uploading artefact blobs to the controller
• [ ] Modifying the oci registry path naming scheme to account for name.

This will not be great for the JVM, as JVM apps share many common Jars. The current addressing scheme allows these jars to be shared between all modules and significantly reduces the amount of data sent over the wire.
