Add dashboard report snapshots feature with CRUD operations. Implemented new database migrations for dashboard_report_snapshots, including report type handling. Updated backend routes and models to support snapshot retrieval and upsert functionality. Enhanced frontend components to integrate report snapshot management, including UI for daily and end-cycle reports. Added tests for new functionality to ensure reliability.
