test(e2e): add negative header-SigV4 rejection suite (backlog#1151 sec-1) RustFS delegates SigV4 verification to the s3s dependency, so nothing in this repo pins OUR end-to-end wiring of it. Add negative_sigv4_test.rs sending REJECTED header-SigV4 requests against a live RustFSTestEnvironment and asserting the HTTP status plus the S3 error code XML: - valid_header_sigv4_request_succeeds (positive control so the negatives cannot pass for the wrong reason) - tampered_signature_returns_signature_does_not_match -> 403 SignatureDoesNotMatch - wrong_secret_key_returns_signature_does_not_match -> 403 SignatureDoesNotMatch - tampered_payload_is_rejected (body != signed x-amz-content-sha256) -> not 200 - skewed_date_returns_request_time_too_skewed (>15min) -> 403 RequestTimeTooSkewed - malformed_authorization_header_returns_clean_4xx (present-not-missing) -> 4xx, never 5xx Signatures are hand-built via rustfs_signer::request_signature_v4 primitives (get_signing_key/get_signature/get_scope) so the test controls the timestamp, secret, signed payload hash, and final signature bytes. Missing-credential negatives are intentionally not duplicated (covered by multipart_auth_test / anonymous_access_test). Refs backlog#1151 (sec-1), master plan backlog#1155.
