Multi-Language Support for Frontend

**Is your feature request related to a problem? Please describe.**
Currently, the website supports only a single language, which limits its accessibility and usability for non-English speaking users.

**Describe the solution you'd like**
I would like to implement multi-language support on the client side. Key features of the solution include:
1. A language selector (dropdown or toggle) for users to choose their preferred language.
2. Localization of all user-facing text using a library like `i18next`.
3. Language persistence using local storage or cookies to save the user’s preference.
4. A fallback language (English) in case a translation is unavailable.

Please share your thoughts or suggestions for additional features that can improve this implementation.
