feat(web): add workflow creation and editing functionality
- Introduced WorkflowNewPage and WorkflowEditPage for creating and editing workflows. - Updated App component to include new routes for workflow management. - Enhanced workflow diagram generation in workflow-mermaid.js for better visualization. - Modified WorkflowsPage to support navigation to the new workflow pages. - Improved HomePage links to direct users to the correct workflow edit paths.
