Flip card in deck viewer on Game Start screen

Is your feature request related to a problem? Please describe.
Variant: Desktop version

When viewing a deck on the Game Start screen, only the front face of double-faced cards is visible. Players would need to switch to Deck Editor or open a web browser to inspect the back, which is very inconvenient.

As in below screenshot, there's no way to see Mistgate Pathway on the back of Hengegate Pathway.

Describe the solution you'd like
Port the existing flip card function of Deck Editor into Deck Viewer

Describe alternatives you've considered
Write this feature from scratch - No go due to no extra benefit while increasing complexity

Additional context
Flip card in Deck Editor for reference
