The previous two-step battingcards→pitchingcards fallback caused card
ID collisions — e.g. card 494 resolving to Cameron Maybin (batting)
instead of the intended pitcher Grayson Rodriguez. The unified cards
endpoint is keyed on globally-unique card instance IDs and carries
player, team, and variant in a single response.
- Single db_get("cards", object_id=card_id) lookup
- Card type derived from player.pos_1 (SP→sp, RP/CP→rp, else→batter)
- team_id sourced from card["team"]["id"] (no get_team_by_owner fallback)
- TestRefractorTestSetup rewritten for the single-endpoint contract
Spec: docs/superpowers/specs/2026-04-11-refractor-test-unified-cards-lookup-design.md
Remove unused `player_name` param from `_execute_refractor_test` and
unused `final` param from `update_embed` closure.
