fix(mcp): drop the duplicated scheduling methods on stubClient (#11323)

master does not compile:

    vet: core/http/endpoints/mcp/localai_assistant_test.go:157:19:
    method stubClient.ListScheduling already declared at
    core/http/endpoints/mcp/localai_assistant_test.go:87:19

Two fixes for the same breakage landed. The four Scheduling methods were
already present at lines 87-99, in interface order after ListNodes, by
the time #11318 merged; #11318 appended its own copy after
GetRouterDecisions. The two blocks sit in different parts of the file, so
git merged both without a conflict and nothing flagged it.

Remove the appended copy and keep the one in interface order. Pure
deletion, no behaviour change.

Verified: go vet clean on ./core/http/endpoints/mcp/, and
go test ./core/http/endpoints/mcp/ passes.
