This update enhances the visual appearance of the PiP (Persistent In-Place) window by aligning its styles with the main softphone. Specifically, calling colors are now accessible, and the ActionButton's border radius is customizable for a more modern look. This improves the overall user experience within the PiP.

### Extend "calling" colors from softphone
This commit makes some styles, like the calling colors, that were initially scoped to the softphone accessible for use in the PiP window as well.

### Adapt border radius of ActionButton
Prior to this commit, the ActionButton only supported circle or pill border radius. This commit enables border-radius customization for greater flexibility.

### Fine-tune the PiP window
This commit adapts the style of the PiP window to make it more consistent with the softphone.
