fix: suppress false "network request failed" error on ticket list scroll

When scrolling through a large tracker, SwiftUI's .task modifier cancels
in-flight pagination requests as rows leave the screen. URLSession
responds with URLError(-999), which was being surfaced to the user as
"The network request failed. Please try again." — even though the
cancellation is expected and benign.

Guard against Task.isCancelled in the catch block so cancellations are
silently ignored; isLoadingMore is still reset unconditionally so the
next scroll attempt retries from the same cursor position.
