Fix SaveList loading issue and form warning

[hiShwetank]

gh pr create --title "Fix SaveList loading issue and form warning" --body "## Issues Fixed:

• ✅ SaveList was stuck in loading state when no saved consoles exist
• ✅ useForm warning in Modal due to missing Form wrapper
• ✅ Code quality improvements (removed unused variables)

Changes:

• LoadingContent: Fixed empty array handling logic to show empty state instead of loading
• SaveList: Added Form wrapper with proper validation to fix useForm connection warning

Testing:

• Empty state now shows correctly when no saved consoles exist
• Form validation works properly for rename functionality
• No console warnings or errors
• Loading state works correctly during data fetching

This fix improves user experience by showing proper empty states and eliminates console warnings."

Thank you for the contribution. The current Community main branch now uses a controlled SaveList rename input and has independent empty-state handling in LoadingContent, so the original issue is already covered by the rewritten implementation. This pull request targets the previous client structure and is now superseded, so we are closing it. If a related problem is reproducible on Community 5.3.0 or later, please open a focused pull request from the current main branch.
