fix(gateway): stop pointing local CLI token mismatches at gateway.remote (#125488)

A local-mode gateway (gateway.mode=local, no gateway.remote block) sent
CLI clients "set gateway.remote.token to match gateway.auth.token" on a
wrong-token connect. That hint is a dead end for local connections since
they resolve credentials from gateway.auth.token directly. The connect
pipeline already records isLocalClient at admission time; thread it into
the auth-failure message so local CLI hints point at gateway.auth.token
(or pairing) while remote CLI hints keep the gateway.remote.* guidance.
