<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Low risk refactor limited to swapping the analytics hook used by
`EndOfSeasonClaimBottomSheet`; behavior should remain the same aside
from how events are dispatched.
> 
> **Overview**
> Migrates `EndOfSeasonClaimBottomSheet` analytics tracking from legacy
`useMetrics` to the new `useAnalytics` hook while keeping event
constants (`MetaMetricsEvents`) sourced from `useMetrics`.
> 
> Updates the associated Jest test to mock `useAnalytics` instead of
`useMetrics`, preserving coverage for the "reward viewed" and "reward
claimed" tracking.
