feat(admin, i18n): enhance admin dashboard and user management with new features and translations

Added the ability to filter admin dashboard data by site code and agent node ID, improving data retrieval capabilities. Introduced new functions for fetching dashboard data based on these parameters. Updated the admin users and roles management components to reflect these changes. Enhanced multi-language support by adding new translations for agent management and permission levels in English, Nepali, and Chinese, ensuring a consistent user experience across the admin interface.
