Add-on purchases (DLC, Season Pass, Battle Pass) previously linked to a parent *purchase* via the `related_purchase` self-FK. When the base game was bought inside a multi-game purchase (e.g. a bundle), there was no per-game purchase to point at — only the whole bundle. Replace it with a `related_game` FK (Game -> Game): an add-on belongs to a *game*, which is unambiguous regardless of how the base game was bought. - models: drop `related_purchase`; add `related_game` (SET_NULL, related_name="addon_purchases"); require it for non-GAME types in `save()`. - forms: replace the parent-purchase picker with a flat `related_game` game search (reusing SearchSelectWidget/_game_options); drop the now unused related_purchase_queryset/RelatedPurchaseChoiceField. - views/urls: remove the obsolete related_purchase_by_game endpoint. - add_purchase.js: drop the parent-dropdown refetch; keep platform auto-fill; retarget the type toggle to #id_related_game. - migration 0020: add -> backfill (related_game = parent's first game by sort_name) -> remove related_purchase. - tests: model validation unit tests + an e2e test for the flat picker. related_game is deliberately game->game so it can later be synced from IGDB's parent_game without schema changes.
