Refactor tile layout to show recent cases

The tile layout has been refactored to display a list of recent cases
instead of the currently active case. This change includes:

- Removing the "current case" view and its associated logic.
- Implementing a new `caseListContent` function to render a list of up
  to 8 recent cases.
- Modifying the main `buildTileLayout` to integrate the new case list
  and a prominent "Neu" (New) button.
- Updating the styling and click handling to reflect the new layout and
  functionality.
