Fix list

The changes that would bring RPKI, the IRR and what's announced into line. Some are deliberate (a route object kept for a backup route, say); the network decides. All 28 are in fix.csv.

Routes: the 08:00 UTC snapshots of 2026-11-12 from 75 RIPE RIS and RouteViews collectors. RPKI: our rpki-client run before the snapshot. IRR: the day's dumps of the five RIR databases and RADB's mirrors. The LEVEL3 and IDNIC databases publish no dump and aren't read, so route objects only there count as none.
