Fix board drag-and-drop phase change not working (#20)

When phase_guard is enabled on a contract, the backend expects
{ phase, confirmed: true } to actually perform the phase change.
Without confirmed: true, the backend returns a PhaseTransitionRequest
instead of ContractSummary, causing the frontend to not update properly.

Add confirmed parameter to changeContractPhase() with default true
for backward compatibility and explicit user actions like drag-and-drop.
