Improve compact feature recommendation panel in onboarding

[harshitarora-in]

Summary

This PR improves the onboarding feature recommendation panel to make it more compact and easier to scan, while keeping the existing selection behavior intact.

Changes included:

• Reduced spacing/padding in the feature cards so more options are visible without extra scrolling.
• Simplified feature recommendations by merging duplicate Otter-based entries into a single recommendation for site builder and form builder.
• Shortened long subtitles for better consistency and readability across templates (including Visualizer, Membership Plugin, and Pods).

Will affect visual aspect of the product
