feat: enhance web server update process with health checks

- Added health check functionality for PostgreSQL, Redis, and Traefik services before updating the web server.
- Introduced a modal state management system to guide users through the verification and update process.
- Updated UI components to display service health status and relevant messages during the update workflow.
- Refactored the update server button to reflect the latest version and availability of updates.
