fix: Harmonization between modal sheets

[g123k]

Hi everyone!

The "old" modal sheets were not aligned with the colors of the Product page.

• Orange indicator added
   

• In dark mode, when the first item was selected, it had the same color as the header
   

• The same for the image source (you can notice a small shadow between the header and the content)
   

• User lists: color harmonization + a brighter button
   

• Users lists in dark mode: color harmonization
