Paul Nothaft c6d401685f fix(security): verify the signature before writing a token to the revocation list
revokeToken() base64-decoded the payload without checking the signature and
inserted a row keyed on id-iat-type, the same key isTokenRevoked() matches
for real sessions. The logout endpoints are unauthenticated, so anyone could
forge a payload naming another user's id, type and login second and log them
out remotely; a far-future exp also left rows that cleanup never swept.

Expiry is still ignored so logging out an expired session stays idempotent.
