refactor: Remove useRecommendationProfile hook dependency and derive state from props in RecommendationsSection

- Replace hook-based state management with direct prop-based state derivation
- Implement getEffectiveOS and isProfileComplete as inline functions using profile prop
- Remove effectiveProfile intermediate variable and use profile prop directly
- Update all references from effectiveProfile to profile throughout component
- Simplify component dependencies by removing hook coupling
