feat(battle-node): BuildMatched consumes MatchContext for player half

selfInfo cosmetics + 30-card selfDeck now read from MatchContext. Opponent
half stays in ScriptedProfiles. DummyCardId / BuildDummyDeck / PlayerMatched
Profile removed. Two new tests lock the deck-idx pairing and cosmetic
flow-through; TypedBodyWireShapeTests + lifecycle tests thread a fixture ctx.
