ENH: Update CTK with visual DICOM browser improvements

List of CTK changes:

BUG: Fix issue with proxy server attribute in ctkDICOMServerNodeWidget2.
     Resolved a bug where the proxy server attribute in the servers settings UI was being cleared at startup.
     The fix ensures that the proxy server option is now correctly retained during initialization.
BUG: Fix sorting of Study Widgets in the Visual DICOM Browser.
     Addressed a bug related to the sorting of study widgets in the visual DICOM browser.
     Previously, the sorting mechanism was compromised when studies shared the same date,

     ensuring proper sorting even when studies have identical dates.
