Fix: add manual check highlight in spectator mode

[Sanket-Kurle]

The red check indicator was not visible when watching other players' games.
This is because gameData is null in spectator mode, and the Chessboard widget was not receiving any check information. As a result, spectators had no feedback that the king was under attack.
So I Updated Board.dart to manually detect check state when gameData == null.
It is using circular shape, not the exact internal check highlighting as we are not passing gameData.

Hi @Sanket-Kurle
Thanks for looking into this issue. I think, however this approach might not be the right one.

As you pointed out gameData of the board Widget in the TV Screen is null, so instead of adding a workaround in board.dart I think the better approach is to pass gameData to the board Widget. To do this I think you need to pass interactiveBoardParams to the gameLayout in tv-screen.dart .

@HaonRekcef i tried way passing gameData to board and doing this i got correct highlight effect to but got some error in test files

you can see where the PR got failed

@Sanket-Kurle As I said, you should not change board.dart at all. The change should be in tv_screen.dart where you will pass interactiveBoardParams to the gameLayout .
