test(config,identity): RED — the previous-KEK edge set master

Config: malformed values blamed on BRIDGE_KEK_PREVIOUS (not BRIDGE_KEK), byte-level equality refusal, both encodings accepted, optional in production. Custodian: dual-open, one clean both-fail error identical to the single-KEK shape, malformed blobs classified as data incidents not KEK incidents (byte-identical with and without previous), cross-AAD refused through the retry path, nil-previous equivalence.
