* [refactor] Organize browser test assets into logical folders

Reorganized test assets for better maintainability:
- groupnodes/: GroupNode feature tests
- groups/: Visual grouping tests
- missing/: Missing nodes/models tests
- links/: Link-related tests
- inputs/: Input widget tests
- widgets/: Widget-specific tests
- nodes/: Node-related tests
- workflowInMedia/: Workflow media files

Updated all loadWorkflow references to use new folder structure.
Fixed programmatic filename references to prevent test failures.
