## **Description**

This unblocks this issue
#25474

The underlying issue is that the remote feature flag controller does not
reset cache on version upgrades, so users will need to close their app
and wait for the feature flag cache to expire before they can see the
new feature.

However the remote feature flag controller change would be pretty large,
so to keep the scope small (and because the explore feature is released)
we will be hardcoding the feature flag to true.

## **Changelog**

<!--
If this PR is not End-User-Facing and should not show up in the
CHANGELOG, you can choose to either:
1. Write `CHANGELOG entry: null`
2. Label with `no-changelog`

If this PR is End-User-Facing, please write a short User-Facing
description in the past tense like:
`CHANGELOG entry: Added a new tab for users to see their NFTs`
`CHANGELOG entry: Fixed a bug that was causing some NFTs to flicker`

(This helps the Release Engineer do their job more quickly and
accurately)

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Medium Risk**
> Forces a previously remote-controlled feature flag on for most builds,
reducing the ability to disable the feature via remote config and
potentially changing user-visible navigation behavior. Risk is limited
to feature gating/UI flow, not security-critical logic.
> 
> **Overview**
> **Defaults the Explore/assets trending tokens feature on in production
builds.** `selectAssetsTrendingTokensEnabled` now injects a
`forcedTrueOverride` (based on `isE2E`) so the flag evaluates to enabled
by default unless running E2E.
> 
> Tests were adjusted to mock `isE2E` and preserve existing selector
expectations, and the `MainNavigator` snapshots were updated to include
the additional Explore-related screens (`ExploreSearch`,
`SitesFullView`, `BrowserTabHome`).
>
