* test(ecstore): extract shared MockWarmBackend into a test-util feature (backlog#1148 ilm-6) The tier/lifecycle integration tests carried two byte-for-byte copies of an in-memory WarmBackend mock — one in crates/scanner/tests and one in rustfs/src/app — plus duplicated register_mock_tier and polling helpers. Both implemented the same ecstore WarmBackend trait. Consolidate them into ecstore behind a new `test-util` feature, exposed via the `rustfs_ecstore::api::tier::test_util` facade: - MockWarmBackend: in-memory WarmBackend with an operation log (for ordering assertions such as "local delete precedes remote remove") and fault injection (FaultConfig): unreachable, HTTP 5xx, credential rejection, injected latency, plus external_remove to simulate an out-of-band remote deletion. - register_mock_tier / register_mock_tier_backend: register the mock into any TierConfigMgr handle (the global manager used by scanner tests or a per-instance one used by the app tests). - xl.meta transition assertion helpers: read_transition_meta, assert_transition_meta_consistent (cross-shard consistency of the status/tier/remote-key/remote-version-id tuple plus free-version count), and free_version_count. - polling helpers: wait_for_remote_absence, wait_for_object_count, wait_for_free_version_absence. Both existing copies now consume this single definition; `rg 'struct MockWarmBackend'` collapses to one. The feature is enabled only from [dev-dependencies], so it never links into the production binary (resolver 3). Designed for downstream ilm-8 (restore lifecycle) and ilm-11 (tier fault injection matrix). Coordinates with #4706 (ilm-2), which adds op-logging to the scanner mock — that op-logging is now part of this shared surface, so #4706 should rebase onto it. Refs rustfs/backlog#1148 (ilm-6), rustfs/backlog#1155. * test(ecstore): fix shared MockWarmBackend usage after main merge - Access stored objects via MockWarmBackend::contains() instead of the now private inner objects map (fixes E0609 after the shared test-util refactor). - Drop dead ReadCloser/ReaderImpl/DiskAPI imports and the unused transition_api test re-exports the mock extraction left behind. - Reword the scanner/rustfs test-util dependency comments so they no longer embed the literal rustfs_ecstore:: path that trips the ECStore architecture-migration guard.
