Fix: Use tuple for padding in Tkinter grid (#283)

In the 'WindowCMDRs' class, corrected padding values for labels by converting lists
into tuples. This resolves the issue where the 'pady' parameter was passed as a list
instead of a tuple, ensuring compatibility with Tkinter's grid system.

Changes made:
- Fixed 'pady' usage in 'CMDR Details' and 'Interaction' labels.
