[Bug] PagingStatus.loadingFirstPage doesn't guarantee that loading is in progress

[MrLepage]

Steps to reproduce

The PagingStatus.loadingFirstPage status can be returned even when isLoading == false, which is misleading given the name suggests an active loading state.

Expected results

PagingStatus.loadingFirstPage should only be returned when:

• No items have been loaded yet (_itemCount == null)
• No error has occurred (!_hasError)
• AND a fetch is currently in progress (isLoading == true)

Actual results

bool get _isLoadingFirstPage => _itemCount == null && !_hasError;
This means PagingStatus.loadingFirstPage can be returned for an initial empty state (PagingState()) even when no fetch is actually in progress.
