test(e2e): add the outbound target matrix and #7082 postmortem (#7092)

test(e2e): add the outbound target matrix and the replication checksum postmortem Defense work for rustfs#7082, the regression rustfs#6895 introduced while fixing rustfs#6853: a fix for one target class changed a client default for every target class and nothing in tree modeled the other classes. - docs/postmortems: timeline, root cause, why four defense layers missed it, and the SOP for changing any outbound client default; AGENTS.md and the adversarial compatibility lens point at it; the two env knobs from rustfs#6895 are documented in docs/operations. - fake_s3_target: reject_aws_chunked_uploads, require_checksum_for_object_lock (Content-MD5 always verified), create_bucket_with_object_lock with a GetObjectLockConfiguration handler, and a TransportSnapshot on every journal record. - replication_target_matrix_test: six object shapes against four target modes with an explicit expectation table; the two rustfs#7082 cells are pinned KnownFailing and fail with an XPASS message once the fix lands. Wired into e2e-repl-nightly, excluded from e2e-full.

 # RustFS Testing

 **Use this when:** you need to pick a test layer for a change, name a test so a gate keeps selecting it, understand why `#[serial]` does nothing under nextest, or handle a flaky test.
