Description

• Companion PR adding the events in Segment

This PR adds the QuickBuy "flash" button entry point to the Market Insights view, mirroring its existing implementation in the parent Asset Details (Token Details) view.

1. Reason for the change: Market Insights already renders the shared TokenDetailsStickyFooter, but it did not expose the QuickBuy lightning button that Asset Details offers. Users reading an asset's Market Insights had no fast path to buy.
2. Improvement/solution: Wire the footer's existing onQuickBuyPress/quickBuyTestID slot in MarketInsightsView, gated behind the same socialAiAssetDetailsQuickBuy feature flag, and open the reused AssetDetailsQuickBuy sheet with the in-scope stickyFooterToken. The sheet reports a distinct market_insights analytics source (a new value added to SocialLeaderboardSource/QuickBuySheetSource), and pressing the button fires a MARKET_INSIGHTS_INTERACTION event with interaction_type: 'quick_buy', parallel to the existing swap/buy handlers.

Note: the new analytics values (market_insights source, quick_buy interaction type) are registered in a companion segment-schema PR so the events pass schema validation.

Changelog

Manual testing steps

Feature: Quick Buy from Market Insights

  Scenario: User opens Quick Buy from the Market Insights view
    Given the socialAiAssetDetailsQuickBuy feature flag is enabled
    And the user is on a token's Market Insights view (non-perps)
    When the user taps the Quick Buy (lightning) button in the sticky footer
    Then the QuickBuy bottom sheet opens for that token
    And a Market Insights interaction event is tracked with interaction_type "quick_buy"
    And the QuickBuy sheet reports analytics source "market_insights"

  Scenario: Flag disabled hides the button
    Given the socialAiAssetDetailsQuickBuy feature flag is disabled
    When the user is on a token's Market Insights view
    Then the Quick Buy button is not rendered
    And the QuickBuy sheet is not mounted
