Multipart upload ids embed the process-global deployment id at both create time and list time. Under plain cargo test (thread-parallel, shared process globals) a concurrently running test that re-initializes a store can swap the global between the two reads, making full-upload-id equality assertions fail spuriously (observed: core::sets::tests::list_multipart_uploads_merges_all_sets_without_pagination_loss failing when run concurrently with bucket::quota tests, passing in isolation).
Add a test-only upload_uuid_suffix helper next to deployment_upload_id and make the affected assertions compare only the decoded <uuid>x<timestamp> suffix. Where suffix normalization changes within-key ordering (base64 alphabet order is not byte order), both sides are sorted before comparison. nextest/CI is unaffected (process-per-test); this only hardens local plain cargo test runs.
