feat: add new localization entries and enhance user subscription links feature

- Added a new translation for "no available hosts found for this user" in English, Persian, and Russian locale files.
- Updated the GetUserSubscriptionLinksFeature to display a message when no subscription links are available.
- Improved the ViewUserModal to conditionally enable queries based on form state.
