Summary of Changes

Hello @hyoban, 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 significantly refactors the internationalization (i18n) implementation within the web application, particularly for marketplace components. The primary goal is to centralize and simplify how translations are handled by moving away from a custom useMixedTranslation hook and explicit locale prop drilling. By adopting the #i18n module and leveraging a global locale context, the changes result in cleaner code, reduced boilerplate, and improved maintainability across various UI elements that require translation.

Highlights

• Migration to #i18n module: The custom useMixedTranslation hook has been removed and replaced with useTranslation from the centralized #i18n module across numerous components.
• Elimination of locale prop drilling: The explicit passing of locale props to marketplace-related components has been removed, simplifying component interfaces.
• Streamlined translation hooks: The useTags and useCategories hooks no longer require a translation function parameter, as they now internally leverage the global translation context.
