Project-level storage usage is incorrect

Summary

Now that we have added the Container Registry size to the project usage quotas page, we need to ensure it also is included in total project storage. From a test project, it looks like that is not currently the case. Overall project storage only shows 1MB, but registry is well over 200.

It is also worth noting that this same 1MB is also shown on the namespace level page:

Proposal

1. Container registry storage should count towards the total on project-level usage quotas page
2. Container registry storage should count towards the total project storage on namespace-level usage quotas page
