Refactor i18n client and server initialization

The refactor includes the removal of clientInstance checks as they are unnecessary. Also, i18n-provider.tsx has been updated to use react-query instead of local state for client initialization. Lastly, error handling has been added to the server initialization process and the @tanstack/react-query package has been added to the project dependencies.
