Course import now fetches both male and female tees, each with their own
per-tee stroke indices extracted from the holes array. Front and back 9
slope/rating are stored per tee for more accurate WHS handicap calculation.
New game creation replaces the 9/18 radio with a course-aware selector:
18-hole courses offer 18 holes, Front 9, or Back 9; 9-hole courses auto-
select. start_hole is stored on the game and used throughout scoring,
handicap calculation, and scorecard rendering.
