Data visualization: Add Date header

This is part of #404+

With RccSegmentBaseComponent and the date picker from #408+ at hand we can complete the header of the data visualization screen.

The starting date together with time period from the RccSegmentBaseComponent determines the end date.

What is to be done?

• Add RccSegmentBaseComponent and the date picker to ReportStackedViewComponent as in the layout below.
• RccSegmentBaseComponent should show three options: 'week', 'month', 'year', default: 'week'
• Add the end date below RccSegmentBaseComponent (right side), initially set to today.
• Add the date picker below RccSegmentBaseComponent (left side); initially set to end date minus the time period from RccSegmentBaseComponent.
• When either date or time period is changed calculate a new end date.
• Output the time frame below the date picker and the end date (will be removed in a later issue)

Calculations

Just for now:

Adding a week means adding 7 days.

Adding a month means adding 4 weeks.

Adding A year means same date next year or 28.Feb for 29.Feb if it does not exist.

Where to start?

• ReportStackedViewComponent: /lib/features/src/report-stacked-view/view/report-stacked-view.component.ts
