Subject: [PATCH 2/2] fix(frontend): resolve test suite timeouts, OOM, and mock
 issues

- Fix BigInt serialization in readModelCache by handling toJSON
- Prevent infinite re-render loop and fake-timer deadlock in useCancelGrace
- Replace slow character-by-character typing with fireEvent in approval tests
- Fix mock timers and expectations in EscrowCountdown, CancelGraceBanner
- Add fake-indexeddb and MSW node server setup in tests/setup.ts
- Add missing useTour mock in Sidebar.test.tsx and update ThemeToggle
