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 focuses on enhancing the internationalization (i18n) system by upgrading core i18next and react-i18next dependencies. The primary goal is to resolve type inference issues with the Trans component, which previously fell back to any due to outdated libraries. Concurrently, the changes standardize how translation keys are referenced by explicitly assigning namespaces to Trans components and refining the i18nKey paths, leading to more robust and maintainable translations across the application.

Highlights

• Dependency Updates: The i18next library has been updated from version 23.16.8 to 25.7.3, and react-i18next has been updated from 15.7.4 to 16.5.0. These updates address issues where the Trans component's type was incorrectly inferred.
• Explicit Namespace Declaration: The Trans component across various UI files now explicitly includes the ns (namespace) prop. This ensures that translation keys are correctly resolved within their designated namespaces.
• i18nKey Refactoring: Several i18nKey values have been adjusted to remove redundant namespace prefixes, aligning them with the new explicit ns prop usage and streamlining translation key management.

Code Review

This pull request effectively addresses the i18n translation issue with the Trans component by updating i18next and react-i18next dependencies. The refactoring to separate the namespace from the i18nKey and use the ns prop is a clean solution that improves code clarity and type safety. The changes are applied consistently across all relevant files. Overall, this is a solid fix that aligns the codebase with the latest library practices.

Pull request overview

This PR updates i18next dependencies to address type issues with the Trans component and adds missing namespace (ns) props to Trans component usages across the application. The dependency updates are substantial version jumps (i18next from v23 to v25, react-i18next from v15 to v16) to fix fallback typing issues where Trans was being typed as any.

Key changes:

• Updated i18next from ^23.16.8 to ^25.7.3 (major version upgrade)
• Updated react-i18next from ^15.7.4 to ^16.5.0 (major version upgrade)
• Added explicit ns (namespace) props to Trans components where they were missing to maintain proper type safety and translation resolution
