fix(mobile): remove duplicate analytics import in ContestScreen (#14386)

## Summary
- Fixes mobile CI failure (typecheck + lint) caused by a duplicate
`import { make, track as trackEvent } from 'app/services/analytics'` in
[ContestScreen.tsx](packages/mobile/src/screens/contest-screen/ContestScreen.tsx).
- The duplicate (out-of-order) copy is removed; the properly ordered
import is retained.

## Test plan
- [ ] CI mobile `verify` (typecheck, lint, lint:env) passes.
