/**
 * Task 13: при ответе создания с launch.deferred=1
 * показывается диалог перегрузки (проект считается созданным).
 *
 * Контракт POST /api/projects → 201:
 *   { data: {...}, launch: { launched: 0|1, deferred: 0|1, balance: OverloadPayload | null } }
 *
 * Если launch.deferred === 1:
 *  - форма закрывается (emit saved)
 *  - открывается ProjectLimitOverloadDialog с payload = launch.balance
 *
 * Если launch.deferred === 0: обычный успех, диалога нет.
