## **Description**

**Bug fix**

Fixed market_insights_displayed always reporting false in the
`TOKEN_DETAILS_OPENED` event by initializing `isLoading` to true in
`useMarketInsights` when a fetch will occur, preventing a race condition
where the tracking callback fired before loading started and
deduplication blocked the correct value

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Low risk state-initialization change in a React hook; main risk is a
minor behavior shift where `isLoading` may start `true` when enabled and
an asset id is present.
> 
> **Overview**
> Fixes a race where market insights tracking could run before loading
begins by initializing `useMarketInsights`’s `isLoading` state to `true`
whenever the hook is enabled and a `caip19Id` is provided, ensuring
first-render consumers don’t see a transient “not loading” state before
the initial fetch.
