fix(details): improve share functionality and localization

This commit enhances the repository sharing logic by adding error handling, localizing UI strings, and improving accessibility.

- **fix(details)**: Added error handling to the share action in `DetailsViewModel` with logging and user feedback on failure.
- **refactor(details)**: Localized "Link copied to clipboard" and share failure messages using string resources.
- **ui(details)**: Added a content description to the share icon in `DetailsRoot` for better accessibility.
