Restore the foretold state when a snapshot is restored

[cuinhellcat]

Fixes #7844.

Problem

Cancel the cast of a foretold card and it comes back to exile without its foretold state, so it can no longer be cast with Foretell.

setCardInCopiedGame restores a card's tapped, face-down, manifested, sickness and state-name, but the two lines for the foretold flags are commented out:

newCard.setSickness(fromCard.hasSickness());
//newCard.setForetold(fromCard.isForetold());
//newCard.setForetoldCostByEffect(fromCard.isForetoldCostByEffect());
newCard.setState(fromCard.getCurrentStateName(), false);

They have been comments since the method was introduced in "Trying to fix gateway dialog glitching" — never active, so this is not re-enabling something that was switched off for a reason. Nothing else restores that state, while CardCopyService.copyCard already carries both flags into the snapshot, so the information is there and simply not read back.

Reproduction

Take a snapshot with a face-down foretold card in exile, turn it face up onto the stack the way casting does, restore. The card returns to exile face down, and isForetold() is false.

Notes

• isForetold() reads the field for a card in exile and derives it from the cast ability elsewhere, so setForetold(fromCard.isForetold()) restores the value that matters and is a no-op for cards that are not in exile.
• No test added, per the note in CONTRIBUTING about agent-added tests. I have one that fails before the change and passes after (the reproduction above); happy to include it if you want it.
• Forge's desktop suite (278 tests) passes with the change.

Closing this in favour of #10294, which already restores the foretold flags as part of its wider pass over the snapshot state. No point spending review time on the same two lines twice.

If #10294 does not move, this is a one-line change to bring back — say the word and I will reopen.
