Extend smoke_test_lockdown.py from two checks to four, all signed by one
throwaway unauthorized key:
kind 1 text note -> BLOCKED (lockdown)
kind 0 profile -> ACCEPTED (profiles stay open)
kind 1059 gift wrap -> ACCEPTED (money path ungated; p-tag a
random recipient, opaque base64 content)
kind 30023 long-form article -> BLOCKED (lockdown)
Prints all four results; RESULT: PASS and exit 0 only if every expectation
holds, nonzero otherwise. Verified offline end to end against a local mock
relay driven by the real plugin decide() (PASS) and against an accept-all
relay (FAIL, exit 1).
