test(security): pin GHSA-m77q STS root-secret token signing (#4823)

test(security): pin GHSA-m77q STS root-secret token signing (sec-7)

GHSA-m77q-r63m-pj89 (intentionally UNFIXED) is that STS session tokens are
signed with the shared root secret: crates/iam/src/root_credentials.rs
token_signing_key() returns the root secret_key, so anyone holding the root
secret can forge STS session tokens. No test named the advisory, and the
existing test_created_sts_credentials_authorize_with_session_token_claims uses
token_signing_key() for both signing and verifying, so it pins "same key signs
and verifies" but not the m77q-specific "signing key IS the root secret" — a
future fix that decouples the STS key from the root secret would pass it
silently.

Add a flow-level pin, test_ghsa_m77q_sts_session_token_signed_with_root_secret,
that captures the advisory's exact signature: (1) token_signing_key() == the
root secret; (2) an AssumeRole-style session token issued with that key decodes
with the root secret and NOT with any other secret; (3) it authorizes through
the STS path. All three assert CURRENT (by-design-vulnerable) behavior, so a
real m77q fix (a dedicated STS signing key) turns them red and forces a
red -> green regression update.

Also GHSA-name the existing characterization test and token_signing_key() with
doc comments and the advisory URL, and update the m77q row in
docs/testing/security-regressions.md. No production behavior changes.
