fix(tui_gateway): drop emit-only session.info from _LONG_HANDLERS

session.info is only ever an emitted event (_emit), never a dispatched
@method RPC, so listing it in _LONG_HANDLERS is dead weight that can
never match a dispatched method name. Remove it from the set and the
test's frontend-polled list to keep _LONG_HANDLERS to real RPCs.
