Joseph Doherty 571066130b fix(server): stop WriteNodeIdUnknown infinite recursion (Server-001) ...

WriteNodeIdUnknown called itself unconditionally as its first statement
— unbounded recursion with no base case → StackOverflowException, an
uncatchable process crash reachable by any client issuing a HistoryRead
on an unresolvable NodeId (remote DoS).

Replace the self-call with the result-slot assignment, mirroring
WriteUnsupported / WriteInternalError. The helper is now internal so the
regression test can pin the StatusCode without a server fixture.

Resolves code-review finding Server-001 (Critical).
