fix: Color-Picker-Cursor erreicht jetzt den rechten und unteren Rand

Browse Source 
updateUI verwendete svCanvas.width (HTML-Attribut, 220px) statt der
tatsächlich gerenderten Breite. Wenn CSS den Canvas größer rendert,
stoppte der Cursor vor dem rechten Rand. Jetzt wird getBoundingClientRect()
verwendet, konsistent mit handleSV.
