test: fix stale AWQ RTN policy expectations
The AWQ default moved to optimized RTN, so normalization now yields
OptimizedRTNConfig for implicit AWQ pipelines and an implicit
AWQConfig carries disable_opt_rtn=False. Update the remaining
assertions and keep the policy-isolation test explicit so it still
verifies that a named RTN variant does not override AWQ's own policy.
The CLI test compares configs before normalize_algorithm_config runs,
so the implicit RTN fallback stays RTNConfig while carrying False.
