* test(ecstore): pin the InvalidRange responses of new_getobjectreader
Both error branches of new_getobjectreader build an ErrorResponse with S3ErrorCode::InvalidRange, and no test observed either code. Pin the code, its wire name and the location fields of each branch before the code type moves to rustfs-s3-types (rustfs/backlog#2743), so a changed code on either branch fails a test. The ecstore test-count row rises by the two tests.
* chore(scripts): add the s3s-to-rustfs-s3-types error codemod
Task T1.2 of rustfs/backlog#2734 (rustfs/backlog#2743) moves S3Error, S3ErrorCode, S3Result and s3_error! from s3s to rustfs-s3-types by script, one crate closure per PR. The codemod rewrites use trees (splitting mixed s3s imports) and qualified code paths, never comments or literals, adds the rustfs-s3-types dependency, drops s3s only from a crate that no longer names it, refuses every file of the s3s edge allowlist, takes --hold for a file whose type is fixed outside the closure, and prints a per-crate census. A second run changes nothing. Its self-test runs under make script-tests.
* refactor(ecstore): take S3ErrorCode from rustfs-s3-types
Output of scripts/codemods/s3_error_to_s3_types.py over crates/ecstore, crates/lifecycle, crates/scanner and crates/replication (rustfs/backlog#2743 batches 1 and 2). The ErrorResponse code field, the two InvalidRange constructions in new_getobjectreader and an unused tier import now use rustfs_s3_types::S3ErrorCode; the variant names and wire names are unchanged. lifecycle, scanner and replication reference none of the four error names. warm_backend.rs and warm_backend_s3.rs are held: they compare against rustfs_s3_client::ErrorResponse.code, which stays the s3s type until s3-client moves.
