/**
 * #6328 (follow-up to #6495) — the dashboard `/api/models` endpoint must also
 * REMOVE paid models when `hidePaidModels` is on (the public `/v1/models`
 * catalog already did via #6495). `openai` has no curated free roster, so its
 * chat models are paid-tier and must disappear when the toggle is on.
 * Rule #18 regression guard for the added filter in src/app/api/models/route.ts.
