The us/eu host strings lived in the driver and were duplicated in the connector-settings resolver. Expose drivers.PostHogRegionBaseURL as the single source and call it from the resolver. Also parse the base URL only inside the absolute-next branch of resolveNextURL, where it is actually used for the host check.
