[FEATURE REQUEST] Translation Support

Hi team,

I’m a user of glance and I find it incredibly useful. To further improve its accessibility and user experience, I would like to request the addition of translation support.

Benefits of Adding Translations:

- Broader Reach: Enable users from around the world to use the app in their native language.
- Improved User Experience: Enhance usability by allowing users to interact in their preferred language.
- Community Engagement: Encourage a more diverse and inclusive user community.
- Increased Adoption: Potentially attract more users by supporting multiple languages.

Implementation Overview
- Internationalization (i18n) Library: Integrate an i18n library such as go-i18n to handle translations.
- Translation Files: Create JSON or YAML files for each supported language, containing key-value pairs for all translatable strings.
- Language Selection: Add a mechanism for users to select their preferred language, either via a config option or by detecting the browser's language settings.
- Dynamic Loading: Load the appropriate translation file based on the user's language selection and update the UI accordingly.
- Fallback Mechanism: Implement a fallback to the default language (e.g., English) for any missing translations.

I believe that adding translations for languages like Italian, Spanish, French, and German could greatly benefit the app.

Thank you for considering this feature request!
