Subject: [PATCH] Add data-testid and accessibility improvements across
 components

Enhancements include:
- Added data-testid attributes to all interactive components for improved e2e testing
- Improved ARIA labels and semantic HTML attributes throughout
- Added aria-label, aria-hidden, aria-describedby, and aria-current where appropriate
- Enhanced form elements with proper aria-invalid and error associations
- Added role attributes to semantic containers
- Improved navigation accessibility with aria-expanded and aria-controls
- Added proper aria-pressed to toggle buttons

Modified components:
- Dialog components (SnippetDialog, CreateNamespaceDialog, DeleteNamespaceDialog)
- Navigation components (NavigationSidebar, Navigation toggle)
- Snippet display components (SnippetCard, SnippetCardActions)
- Snippet manager components (SnippetToolbar, SnippetGrid)
- Snippet editor components (SnippetFormFields, InputParameterList, InputParameterItem)
- Namespace management (NamespaceSelector)
- Layout components (PageLayout)

These changes improve both automated testing capabilities and accessibility for users with disabilities.
