[Feature]: Implement Internationalization (i18n)

**App Name:** `web`

**Is your feature request related to a problem? Please describe.**
The application currently only supports English, limiting its accessibility and usability for a global audience.

**Describe the solution you'd like**
Implement an internationalization (i18n) framework (e.g., `next-i18next` or similar) in the frontend application to allow for translation of UI elements and content into multiple languages.

**Describe alternatives you've considered**
None, as the goal is to support multiple languages.

**Additional context**
This will help expand the project's reach to non-English speaking users.
