[Feature] Implement Internationalization (i18n) Support

[DigHuang]

🚀 Feature Request

Description

We want to make ValueCell accessible to a global audience! currently, all text in the application is hardcoded in English. We need to implement an i18n solution to support multiple languages.

Goals

• Set up an i18n library (e.g., react-i18next).
• Extract hardcoded strings into localization files (e.g., locales/en.json).
• Ensure the UI adapts correctly to text length changes.
• Naming Convention: Use nested keys for grouping (e.g., home.welcome_message)
