Add bpInTargetCount90/SpanDays90 to snapshot extras OpenAPI

buildExtras emits bpInTargetCount90 + bpInTargetSpanDays90, but the
registered extras schema (additionalProperties: false) omitted them, so a
strict iOS decoder would reject the dashboard snapshot. Declare both as
nullable integers to match the runtime shape and regenerate the spec.
