Enhance channel management with apply report feature

Added functionality to display a consolidated apply report for warnings after applying channel templates, improving user experience by reducing clutter from individual warning notifications. Updated the ChannelDetail component to manage the new report state and integrated the ApplyReportDialog for displaying the report. Refactored the Problems component to utilize a new PlanningWarnings component for better organization of warning messages. Localization strings were updated to include new report-related texts in both English and Russian.
