* fix(ecstore): add fallible erasure construction
(cherry picked from commit bd148b20f7)
* fix(ecstore): resolve storage parity per pool
(cherry picked from commit c05c2cb24b)
* fix(ecstore): keep carved per-pool parity core self-contained on main
Fixups so the cherry-picked fallible-erasure + per-pool-parity core builds standalone on current main without the excluded scope-creep commits:
- runtime/sources.rs: re-add backend_storage_class_parities (removed by the per-pool commit; its rebalance caller was updated in an unrelated reporting commit that was left out). Reimplemented over the snapshot API, behavior-identical.
- config/mod.rs: rename the storage-class publish test module (main independently added a mod tests, so the cherry-pick collided).
- rustfs storage_api.rs + startup_storage.rs: route the storage-class ENV consts through the startup storage facade and use a local const for the erasure-set-drive-count env name, satisfying the layer/facade guardrail (main's guardrail is stricter than when the core was authored).
* fix(ecstore): use struct-init in erasure test helper to satisfy clippy field_reassign_with_default
The cherry-picked fallible-erasure commit's `erasure_with_invalid_dimensions` test helper built `Erasure` via `default()` then reassigned fields, which trips `clippy::field_reassign_with_default` under `-D warnings` (only surfaced by `--all-targets`, which lints test code). #4977 fixed this in a later commit that was not part of the carved core. Use struct-init with `..Default::default()`, matching #4977's final form.
* fix(rustfs): gate the test-only storage-class ENV facade re-export behind cfg(test)
The ENV constants (INLINE_BLOCK_ENV/OPTIMIZE_ENV/RRS_ENV/STANDARD_ENV) re-exported through the startup storage facade are only consumed by a #[cfg(test)] test in startup_storage.rs, so in a non-test lib build the re-export is unused and trips -D unused-imports under clippy --all-targets. Gate it with #[cfg(test)], matching #4977's final form.

is_all_not_found and is_all_volume_not_found delegated to
is_err_bucket_not_found, which matches StorageError::DiskNotFound. When
every erasure set in every pool was unreachable, the per-set aggregate
DiskNotFound slice was classified as "all not found", so list_merged
returned Ok(empty) and walk_result_from_set_errors was fed an
availability failure disguised as an empty listing. Clients saw a
successful empty ListObjects and mistook a full outage for an empty
bucket.
Introduce is_err_strict_not_found (FileNotFound / VolumeNotFound /
FileVersionNotFound / ObjectNotFound / VersionNotFound, excluding
DiskNotFound) for is_all_not_found, mirroring MinIO's isAllNotFound and
DiskError::is_all_not_found. Give is_all_volume_not_found its own
is_err_strict_volume_not_found (VolumeNotFound / BucketNotFound, minus
DiskNotFound) so genuine volume/bucket absence still surfaces while a
missing object under an existing volume is not escalated. Add
is_all_disk_not_found and a pre-check in walk_result_from_set_errors so
an all-offline slice surfaces DiskNotFound instead of being swallowed as
an empty listing, while partial outages (a healthy set present) stay
tolerated as before.
Regression tests cover all-DiskNotFound rejection, genuine not-found
acceptance, volume-not-found semantics, partial/empty short-circuit, and
the walk full-offline vs partial-offline paths.

test: add insta snapshot test for storage error display format
Add snapshot test to detect unexpected changes in StorageError
display format. This catches output format regressions that
traditional assert tests might miss.
