Add i18n (internationalization) support to the project #21
Description
Add internationalization (i18n) support to the project to enable localization and translation of the user interface. This will allow Capturist to be accessible to users in multiple languages. Consider adopting a widely used JavaScript i18n library, set up language files, and provide an example translation.
Tasks:
- Evaluate and select an i18n library
- Integrate i18n framework into the codebase
- Refactor UI components to use translation keys
- Add English as the default language
- Provide structure for additional languages (e.g., Spanish, French, etc.)
- Add developer documentation for updating translations
