InsertSetRow first-appearance badge renders 'Debut' for Entertainment/non-athlete sets; 'Rookie' unchanged everywhere else. RC badges unchanged.
"Debut" instead of "Rookie" for characters
On entertainment sets, the first-appearance flag (is_rookie) marks a character's debut rather than a rookie season, so "Dark Gwenpool — Rookie" read wrong.
- The InsertSetRow first-appearance badge now reads "Debut" on Entertainment sets and "Rookie" everywhere else. This retroactively corrects Marvel Comics, Disney, and the Sapphire set.
- Label-only change — the underlying flag, its value, and which cards show a badge are all unchanged. The compact "RC" badges elsewhere are untouched.
- Guarded so sports and mixed sets can never be affected: the label only flips for the Entertainment category.
