## **Description**

Some bug fixes on Trending plus some improvements:

Improvements:
- Search results were not the same when searching on omnisearch and when
searching on each of the pages separately, I have moved the search to
each of the hooks so that search is handled there (also removes the need
of getSearchQuery from the sectionsConfig)
- Removed the need for a keyExtractor in the sectionsConfig
- Homogenized and reworked Skeletons so that the experience as a user is
better

Bug fixes:
- Clicking on a native asset within trending throws error and makes the
app restart

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Moves search filtering into section hooks, standardizes skeleton UIs,
and fixes navigation for native tokens from Trending.
> 
> - **Search architecture**:
> - Move filtering into hooks: `useTrendingSearch`,
`useSitesData(searchQuery, limit)`, `usePerpsSearch`, and sections via
`useSectionsData(searchQuery)`; remove per-section
`getSearchableText`/key extractors.
> - `useTrendingSearch`: filters trending by query, merges with search
API, dedupes; exposes loading; tests added.
> - `useSearchRequest`: `chainIds` optional; debounced explore search
uses section-provided data.
> - **Perps**:
> - Add `filterMarketsByQuery` in `marketUtils` (+ tests) and use in
`usePerpsSearch` and sections.
> - **Sites**:
> - `useSitesData` now returns all sites and filters locally by
`searchQuery`; API fetch unchanged; tests updated.
> - `SitesFullView` passes `searchQuery` to hook; removes local
filtering.
> - **Trending tokens**:
> - `TrendingTokenRowItem`: refactor badge/source helpers; add
native-token nav support (`isNative`/`isETH`) and memoization; color
helper for pct change; tests for ETH/MATIC/native cases.
> - `TrendingTokensFullView`: uses unified search results; updates
skeleton rendering.
> - **Explore search & sections**:
> - `useExploreSearch`: show top items on empty query; delegate
filtering to sections; improved loading/debounce handling.
> - Switch list `keyExtractor`s to stable index-based keys per section.
> - `SECTIONS_CONFIG`: pass `searchQuery` to hooks; unify Perps
skeleton.
> - **UI/Skeletons**:
> - Rework `TrendingTokensSkeleton` and `SiteSkeleton` to consistent
44px circular icon + text rows; tests adjusted.
