[GUI] Need to resize Examine -> Certificate Details window

[rufik]

Is your feature request related to a problem? Please describe.
A little bit :) I'd like to see all the details within "Subject" line, but right now the window is not resizable and line text is truncated.

Describe the solution you'd like

Describe alternatives you've considered
None.

Additional context
None.
