fix: empty board + state stuck in Dialogue

- BoardManager.SetupBoard: fallback to PlacePieces() when campaign
  identities are not configured (prevents empty board)
- CampaignManager: only transition to Dialogue state if StartDialogue
  returns true (prevents state override when dialogue fails)
- Same fix for outro dialogue transition
