Update Todos

Chapman: format-valg i new-round.tsx + tournament-program.tsx (session)

Nassau: nytt vindu-resultatvisning i round-detail.tsx + session-scorecard.tsx

Københavner: format-valg + poengtabell-visning i individual-tournament-detail.tsx

Bingo Bango Bongo: format-valg + per-hull picker + poengtabell

Flaggturnering: format-valg + nedtelling/resultatvisning

Shamble: format-valg + best_n + lagvisning (frittstående + org-lag)

Money Ball: format-valg + lineup_order + lagvisning (frittstående + org-lag)

High-low-high: format-valg + løpende poeng-resultatvisning (alle 3 flater)

Ekte produksjonsbuild -- FERDIG, kompilerte rent (27 ruter)

Browserverifisert alle åtte formatene -- fant og fikset ekte backend-bug (side-handicap-recompute)

Rullet ut mot ekte teecup_api/teecup_frontend -- FERDIG, health checks grønne, teeoff.no upåvirket
Rullet ut live 2026-07-30. Frontend for alle åtte nye turneringsformatene (Chapman, Nassau, Københavner, Bingo Bango Bongo, Flaggturnering, Shamble, Money Ball, High-low-high) er nå bygget, browserverifisert og live — dekker alle tre flatene (frittstående runder, org-lagturneringer, org-individuelle turneringer). Fant og fikset én reell backend-bug underveis (side-handicap ble ikke regnet på nytt når en deltakers HCP ble satt/endret etter at de allerede var tildelt en side). Ingen migrasjon i denne runden, teeoff.no upåvirket. ADR-039/åtte-formater-arbeidet er dermed helt ferdig, backend og frontend.
