feat: implement internet path functionality with backend support

Added internet path settings and snapshot management to the application. This includes new database tables for internet path settings and snapshots, API routes for fetching and managing internet path data, and integration into the dashboard and data collection pages. Enhanced the scheduler to support internet path jobs, ensuring regular data collection and updates. Updated relevant types and interfaces to accommodate the new functionality.
