feat-homescreen - Add toggle and mirrored sizing for Modern cards on My Media row

[mattsigal]

Pull Request

Summary

Adds a user preference toggle modernCardsOnMyMediaRow (default true) under Home Screen settings when Modern row layout is active. When toggled off, My Media cards remain within the modern row layout engine and display static landscape artwork that mirrors the exact dimensions of the modern expanded focused thumbnail on neighboring rows across all card display sizes.
