Add items param to trackRecommendationResultsView for variation ID su…

[Sher-Bakhodirov]

Summary

Adds an items: [CIOItem]? param to trackRecommendationResultsView so callers
can pass variationIDs. Mirrors trackBrowseResultsLoaded; items is preferred over
customerIDs when both are set. Backwards-compatible.

Why one method, not two overloads

A separate items: overload would be ambiguous — with defaults on every param,
calls omitting both customerIDs and items (e.g.
trackRecommendationResultsView(podID:)) fail to compile. A single method
matches trackBrowseResultsLoaded and stays backwards-compatible.

Pull request overview

This PR extends the public tracking API for recommendation result views to accept full CIOItem objects (enabling variationID support) while preserving the existing customerIDs path for backwards compatibility. It mirrors the established items behavior used by other tracking endpoints (e.g., browse/search results loaded), including preferring items over customerIDs when both are provided.

Changes:

• Add items: [CIOItem]? parameter to ConstructorIO.trackRecommendationResultsView.
• Extend CIOTrackRecommendationResultsViewData to serialize items (including variation_id and sponsored listing fields) and prefer it over customerIDs.
• Add/extend unit tests to cover items payload serialization and precedence.

Code Review

This PR correctly adds items: [CIOItem]? to trackRecommendationResultsView, mirroring the existing trackBrowseResultsLoaded / trackSearchResultsLoaded pattern, and the serialization logic, test renames, and new test coverage are all solid.
