Function useLoadingState

useLoadingState(
    initialState?: boolean,
): {
    activateLoadingState: () => Promise<void>;
    deactivateLoadingState: () => Promise<void>;
    isLoading: Ref<boolean, boolean>;
}
A standalone isLoading ref with activate/deactivate actions, each awaiting nextTick() so a template update triggered by the flag has actually happened before the caller continues.

Ported from luv-autoq-frontend. More general than useApi's built-in isLoading (which is tied to one callback) - useful for multi-step flows where the loading state doesn't map to a single async call.
Parameters
- initialState: boolean = false
Returns {
    activateLoadingState: () => Promise<void>;
    deactivateLoadingState: () => Promise<void>;
    isLoading: Ref<boolean, boolean>;
}
