SkinnedUI: bug fixing and improvements:

* SPE-1945 : LINUX - Black background in dark mode in search - "Category"
* SPE-1941 : Font size is applied for old PS version (app_config key for font size is changed to "font_pt_size")
* SPE-1939 : Preferences : PS widows have incorrect dims when used max font size
* SPE-1943 : Fixed gtk resize popup window (Manually merged 60dbf71cd6 )
* SPE-1942 : Linux specific: Brim check button on sidebar jumps
* SPE-1944 : PrusaConnect URL is missing in physical Printer
+ Changed icon which is used to comboboxes
