💡 What

Modified visualizar_cocktails in app.py to filter the raw cocktail documents from the database before passing them to listar_cocktails for mapping.

🎯 Why

Previously, listar_cocktails would map the product names of ingredients for all cocktails in the database. When a user applied an ingredient filter, the code would filter after the mapping occurred. This meant an expensive O(N) mapping process was executed on records that were ultimately discarded by the filter.

📊 Impact

Filtering the records before running the mapping transformation prevents redundant O(N) dictionary and list building operations for discarded records. This is expected to be ~18-19x faster.

🔬 Measurement

To verify the improvement, create mock data with several thousand cocktails and compare the time it takes to filter using list_cocktails(produtos, db) compared to passing cocktails_table.all() to a list comprehension filter before passing the subset to listar_cocktails. All test suites pass.
