feat: implement chart modal with report functionality for cable monitoring

- Add chartTitle state management to kabelueberwachungChartSlice with "Messkurve"/"Meldungen" options
- Update IsoChartActionBar dropdown to show current chartTitle value with proper binding
- Implement conditional rendering in IsoChartView between IsoMeasurementChart and Report components
- Create Report.tsx component using same data structure as MeldungenView (Meldung type)
- Add slot-based message filtering for specific cable monitoring units (KÜ)
- Integrate getMessagesThunk for consistent data loading across components
- Style Report component with consistent table layout, German date formatting, and Littwin branding
- Enable seamless switching between measurement chart and filtered messages in modal
