Deletes three blocks of commented-out code that can never be revived: seven dead tokio::tests plus ~20 commented use statements at the tail of ecstore's store/list_objects.rs test module (all hardcoded to a developer's personal machine path), the commented test_extract_claims in policy/utils.rs, and the commented-out pre-strum AdminAction enum draft in policy/action.rs (the live enum below it is untouched).
Also rewords two doc comments on the bucket-metadata inline-data interop test to drop the personal attribution while keeping the technical content, so the corpse check (rg weisd) now returns zero across the repo.
Ref rustfs/backlog#1836 (PR2).
