/**
 * Issue #2929 — Fire Pass (fpk_*) API keys incorrectly marked as unavailable
 * when the models endpoint returns 403.
 *
 * Fireworks Fire Pass keys return `403 "Fire Pass API keys are not authorized
 * for this route."` on /models while still serving chat. That route-restriction
 * 403 used to fall into the api-key-403 branch (→ AUTH_ERROR retryable fallback)
 * or the generic "all other errors" default (→ transient cooldown), either of
 * which cools down / marks the connection unavailable.
 *
 * A route-restriction 403 must be treated as benign for connection health:
 * shouldFallback=false, no cooldown.
