fix(mcp): teach the assistant test stub the scheduling methods (#11318)

#11228 added ListScheduling, GetScheduling, SetScheduling and
DeleteScheduling to localaitools.LocalAIClient but did not update
stubClient, the hand-written test double in the mcp endpoints package.
The package therefore fails to typecheck, which takes out both lint and
tests on master:

    cannot use stubClient{} as localaitools.LocalAIClient value in
    argument to h.Initialize: stubClient does not implement
    localaitools.LocalAIClient (missing method DeleteScheduling)

Red on 8f74f74b, fd4ec083 and 8a68f357; green on cd62e8ff, the commit
before.

Add the four methods with the same inert bodies the rest of the stub
uses. The real implementations are covered in the localaitools suites;
this double only exists so the holder can be constructed.
