fix: correct link copy function and add i18n support

- Updates shortLink copy function to use .value for reactive reference
- Adds i18n translation support in Editor component

The copy function was trying to access the shortLink directly instead of its value, which would fail in Vue's reactive system. This fix ensures proper reactivity handling when copying links.
