ESPN's IndyCar standings aggregate lags hours behind a race finish (Palou
stuck at 374 an evening after Mid-Ohio, vs. his true 409/P1). Add an
OcBlacktopIndyCarStandingsAdapter that reads the fresher OC Blacktop feed and
delegates to the existing ESPN IndyCarStandingsAdapter on any failure (missing
key, network error, empty payload, or schema drift) so a flaky third party
never breaks the sync.
Per-row validation throws on missing id/name or unparseable position/points to
route to the fallback rather than overwriting real standings with zeros, while
still keeping legitimate 0-point backmarkers.
