refactor(layout-config): improve error handling and data normalization

- Remove unused error parameter from catch blocks for cleaner error handling
- Normalize date objects to ISO strings in layout configurations data
- Fix dialog message formatting by removing unnecessary quotes
- Remove unused BadgeIcon import from LayoutSectionCard
- Update page params type to use Promise for Next.js 13+ compatibility
