fix: correct settings JSX structure, update display name, improve params handling

- Fix extra closing Box tag in SettingsPage causing blank display
- Change display name from 'Sealed Secrets Plugin for Headlamp' to 'Sealed Secrets'
- Use default values for params to avoid undefined in hooks (fixes retry button issue)
