fix ATLAS reference for T-PERSIST-003

[LPirch]

I've just stumbled across this threat and noticed that it references the wrong ATLAS ID.

previously: "AI Supply Chain Compromise: Data" (AML.T0010.002)

now: "Modify AI Agent Configuration" (AML.T0081)

Keep ATLAS mapping table in sync with threat ID

Changing T-PERSIST-003 to AML.T0081 here leaves atlas_technique_mapping inconsistent, because the same threat is still listed under AML.T0010.002 (see threats.yaml lines 850-852). This creates conflicting ATLAS classifications for one threat, so consumers that render/group from the mapping block will keep showing the old technique and not reflect the new one.
