PointsRankEntry

One row in a `PointsRank` standings table (spec §4/§5/§6) — an accumulated-points ranking, never a W/L/T record. `rank` is 1-based in table order, already decided by the countback sort ([`crate::stats::standings::racing_drivers_points_rank`] / `racing_constructors_points_rank`); `points`/`wins`/`events` are summed/counted from stored phase rows (`racing_result`) — never a fabricated zero for a shape (W/L/T) this table doesn't have.
