fix: Smooth transition for Container Registry enable switch

[yomybaby]

Resolve #2880

Changes:
Updates the container registry list fetch behavior to use different Apollo fetch policies based on whether it's the initial fetch or a subsequent reload:

• Initial fetch uses store-and-network to show cached data while fetching fresh data
• Subsequent fetches use network-only to ensure fresh data

Rationale:
This change optimizes the user experience by showing cached data immediately on first load while still ensuring up-to-date data on manual refreshes.
