feat(Kue705FO): replace switch buttons with direct chart access buttons

- Remove Schleife/TDR switch buttons and separate Messkurve button
- Add "TDR Messkurve" and "Schleife Messkurve" buttons for direct chart access
- Each button opens the corresponding chart type directly
- Improve user experience by reducing clicks needed to access specific charts
- Clean up unused imports (handleButtonClick, tdrLocation, tdrActive)
