v5.12.2

What's new:

• Back button now correctly returns to the previous page with all filters and pagination intact
• Navigation state persists through external redirects via sessionStorage
• Automatic cleanup of stale navigation data (older than 1 hour)
• Uses browser history when no saved navigation state is found

Technical changes:

• Added navigationState.ts helper with saveNavigationFrom, getNavigationFrom, and clearNavigationFrom functions
• Updated BackButton, CreateButton, EditAction, and Form components to use new navigation state
• Extended RouterLocationState interface with from field

Benefits:

• Preserves user context when navigating between CRUD pages
• Eliminates loss of filters and pagination after editing or redirects
• Provides more predictable and consistent navigation behavior across the admin interface
