Summary of Changes

Hello @samuelsarabia-adyen, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request primarily focuses on implementing a new internal PBL Store Selector component, which includes a dedicated useStores hook for efficient data fetching and state management of available stores. Concurrently, it refines the Select component's onChange event handling by introducing and enforcing a strict SelectChangeEvent type across multiple existing components, thereby enhancing type safety and consistency throughout the codebase. The Select component also gains a new feature allowing custom rendering of its button content.

Highlights

• PBL Store Selector Component: Introduced a new internal StoreSelector component, designed to display and manage a list of stores.
• useStores Hook: Added a new hook, useStores, responsible for fetching store data from an API endpoint and managing the selected store state.
• Strict SelectChangeEvent Typing: Normalized and strictly typed the onChange event parameter for the Select component across various files, improving type safety and developer experience.
• Custom Select Button Rendering: Enhanced the Select component to support custom rendering of its button content via a new renderButtonContent prop.

Code Review

This pull request introduces a new StoreSelector internal component and a corresponding useStores hook for data fetching. A significant improvement is the normalization of SelectChangeEvent for stricter typing across various components, which enhances type safety. The implementation is solid, but I've identified a few areas for improvement, including a critical case of code duplication, a redundant test, and an opportunity to simplify component logic for better maintainability.
