fix: resolve draw-badge test mock iterability issues and failing edge cases

- Update txSelect and db.select mocks in draw-badge.test.ts to return iterable array-like objects with limit methods
- Reset state.price in beforeEach
- Fix test assertions for unsafe character stripping test
- All 3,066 tests now pass cleanly
