feat(home): align desktop cards with Figma actions

- Update desktop header actions to match Figma: remove the standalone desktop favorites button and style the wallet connect pill with the wallet icon while allowing localized labels to expand.
- Replace favorite action with the Figma bookmark SVG and hover state; replace download cloud with the provided Figma SVG.
- Align official recommendation cards with the Figma card structure, colors, and bottom action row.
- Rework popular rows to the Figma desktop rhythm with 90px rows, wide thumbnails, rank area, and right-side action buttons.
- Add a dedicated desktop LatestUpdateCard for Figma-style latest-update masonry cards with flexible text-driven heights instead of fixed card heights.
