"""
Flight/gruppe-scoping i ScoreTab (ADR-099, 2026-08-21). list_round_participants
speiler nå ut tournament_round_group_id + is_self per rad, slik at frontend kan
la score-føringsskjermen default til brukerens egen utslagsgruppe i stedet for
hele feltet. is_self beregnes server-side (ikke rå user_id, samme is_mine-
mønster som rounds.py) for ikke å lekke andre spilleres kontokobling.
