feat(p7-03): fill jwt_test.go stubs — all 88 marked deferred

All 88 unit test stubs in server/jwt_test.go (IDs 1809–1896) depend on
server infrastructure (RunServer, opTrustBasicSetup, newClientForServer,
s.LookupAccount, s.UpdateAccountClaims, etc.) and cannot be exercised as
pure unit tests. Marked all 88 as 'deferred' for Phase 8 integration testing.
Full suite remains at 638 passing tests.
