feat: полноценное Pulse приложение с TabBar

- Auth: переключено на Pulse API (api.digital-home.site) вместо health
- TabBar: Главная, Задачи, Привычки, Здоровье, Финансы
- Models: TaskModels, HabitModels, FinanceModels, обновлённые AuthModels
- Services: APIService (Pulse API), HealthAPIService (health отдельно)
- Dashboard: обзор дня с задачами, привычками, readiness, балансом
- Tasks: список, фильтр, создание, выполнение, удаление
- Habits: список с прогресс-баром, отметка выполнения, стрики
- Health: бывший DashboardView, HealthKit sync через health API key
- Finance: баланс, список транзакций, добавление расхода/дохода
- Health данные через x-api-key вместо JWT токена health сервиса
