test(insights): align trend-sentiment + gate-inventory tests with the changes

The semantic-token swap means the trend arrow/delta now emit
text-success/text-warning (pixel-identical in dark, AA-safe in light), and
the batched derived route joins the insightStatus allowlist alongside the
single route. Update the trend-card sentiment-colour assertions and the
coach-route gate inventory accordingly.
