Wrap getExpenses.awaitOne, upsertExpense.await, getRecurringExpenses.awaitOne
and upsertRecurringExpense.await in withContext(Dispatchers.IO) { ... } so
the suspending Room calls run off the main thread. State-flow updates stay
inside screenModelScope.launch, which is Main-bound, and execute after the
withContext block returns.
