Card grid for desktop reveal and single-pick dialogs

Example using Inquisition of Kozilek

Before:

After:

---

• Add card art selection dialog to desktop deck editor #10546 introduced CardImageGrid as a general utility for the deck-editor art picker; this PR takes advantage of it for desktop reveal and single-pick dialogs, so reveal/discard/exile prompts show thumbnails instead of a names-only list.
• CardImageGrid is now generic over the item type via a CellAdapter; forPaperCards keeps the deck-editor art picker, forCardViews is the new in-match path.
• Non-CardView ListChooser dialogs (counter types, colors, modes, spell abilities) stay on the text list — there's no card art to render.
• Multi-pick CardView selection isn't part of ListChooser traffic at all — it routes through DualListBox (two-column ordering) or InputSelectCardsFromList (clicking cards on the battlefield), which are separate widgets with their own UX. Bringing the grid look to those is a larger change and out of scope here.
• Desktop GUI only — no protocol, serialization, or game-state changes; wire format and delta sync are untouched.

Potential follow-up PR applying same visual concept to DualListBox, with drag-and-drop support:

doesn't really convince me:
might be ok visually for ~3 cards but a bigger list? 😱

and the way it looks right now usability worsens without:
a) being able to see current Oracle
b) using keyboard to type your selection
c) much more of boardstate hidden behind dialog

If anything that Inquisition of Kozilek could instead let you pick from the players hand view directly (which would also align more with other GUI workflows)...

I guess my view is: it's a card game, should try and surface the cards rather than plain text as much as possible in UI widgets so long as it doesn't seriously compromise usability.

I think some of those usability issues above can probably be surmounted:

• In my local duallistbox implementation it caps at (off the top of my head) 7 cards; any more than that just uses plain text.
  Could apply that to both widgets so you get card visualisation for most decisions involving small numbers of cards and the text list for large lists.

• can incorporate search filter

• could have it scale widget size to some capped amount of window space so oracle/card image panels remain visible

• could add "view battlefield" button to minimise/restore widget

Agree with your Kozilek discard suggestion though, I'll look into that further...
