Rangefinder-koordinater for offisielle (TeeOff-koblede) baner (migrasjon
079, ADR-081). To lag med tester:

1. `get_target_points()`/`resolve_match_course_key()` -- de delte
   byggeklossene direkte, uavhengig av hvilket av de tre kallestedene

2. Integrasjon mot alle tre endepunktene (frittstående runde, individuell
