docs: document Sprint 3 save and autosave coverage
Document card instance persistence and the validateDeck fix Adds a Card Instance Persistence section covering the CardInstance refactor's impact on Save/Load (PR #243) and the partial-mutation validation bug caught in review (PR #248). Updates the Data Model table, File Format example, and Testing section to match the new DeckSaveData schema (per-card instanceId/cardId/upgradeLevel instead of a flat cardId list).
Update: menu integration/styling section, pause-menu note, new test from #223 - Adds Menu Integration & Styling section documenting the Load Game crash fix, MenuTheme styling pass, and the texture-caching fix caught in review - Updates the now-stale Team 4 (menu) cross-team note to reflect the actual pause-menu abandon-encounter fix (PR #220) and its known limitation (abandon is a no-op after a save/load reload, flagged by Zaidan) - Documents the new generated-map save/restore test added in #223
