fix(battle-node): expand rank-battle deck by DeckCard.Count

Browse Source 
BuildForRankBattleAsync projected deck.Cards.Select(c => c.Card.Id),
discarding Count. DeckCard is count-based (one row per unique card +
a Count), so a 3-copy card shipped to the node as a single in-battle
card -- matched decks showed 1 of each card instead of the real count.

Expand each row by its Count so SelfDeckCardIds carries one entry per
physical card. TwoPick path is unaffected (flat per-pick list).

Add a regression test seeding 3+2+1 copies (failed Expected 6/was 3).
