<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Medium Risk**
> Medium risk because it changes the points-events fetching pipeline
(new `type` query param, caching key changes, and request-cancellation
logic), which could impact activity feed freshness/pagination if edge
cases were missed.
> 
> **Overview**
> Adds an **Activity Tab dropdown filter** that lets users fetch points
activity by earn type, driven by season-provided `activityTypes` and new
i18n strings.
> 
> Extends `usePointsEvents` and the rewards backend to support
**type-filtered points events**: the hook now accepts `type` and
`enabled`, cancels in-flight first-page/pagination requests when
dependencies change, and the RewardsController/DataService include
`type` in API requests and cache keys.
> 
> Updates `SelectOptionSheet`/`OptionsSheet` UI (design-system icon,
sorted options with `all` pinned, new close header) and tweaks a few
Rewards visuals (smaller icons, bonus text color), with substantial
test/snapshot updates to cover filtering and new fetch behavior.
