Code Review

This pull request refactors the data layer to utilize Firestore pipelines for dynamic aggregation of recipe ratings, like counts, and popular tags, while also introducing a new search capability. Review feedback identifies a critical bug where field("id") is incorrectly used to reference document IDs, which will likely result in null values. Additionally, the filtering logic is missing necessary dynamic field calculations required for UI consistency and popularity-based sorting, and an unused subquery for like counts was noted as an optimization opportunity.
