improvement(ui): share workflow preview actions

[BillLeoutsakosvl346]

Summary

• Share the three embedded workflow preview actions through one product component using EMCN Button and Tooltip.
• Preserve the 24px geometry, solid surface, accessible labels, icons and open/expand handlers.

Type of Change

• Refactor / maintainability improvement

Testing

• Full workspace type checks, lint, repository audits (including import and API validation), generators and docs checks pass.
• External source comparison confirms caller logic and content are unchanged.
• Original and extracted components have matching computed styles in light/dark browser fixtures; keyboard, disabled and expansion behavior checked. These are isolated fixtures, not full authenticated product flows.
• Relevant existing tests pass. No landing-page changes or audit tooling included.

Checklist

• Code follows project style guidelines
• Self-reviewed my changes
• Tests added/updated and passing
• No new warnings introduced
• I confirm that I have read and agree to the terms outlined in the Contributor License Agreement (CLA)

The PR appears safe to merge with no outstanding correctness or repository-rule issues.

Summary

This PR extracts the shared embedded-workflow preview action into a reusable component while preserving each caller’s label, icon, positioning, and click behavior.

• Centralizes the EMCN button and tooltip presentation.
• Keeps workflow open and execution drill-down handlers at their existing call sites.
• Fixes the previously reported props API issues by using an interface and excluding the fixed type prop.

Before / after visual comparison

Workflow preview open/expand actions share WorkflowPreviewAction while retaining their existing small bordered button treatment.

Left = before; right = after.

Rendered component fixtures with application CSS and local data, rather than authenticated product-page screenshots. These are representative visual examples, not end-to-end behavior coverage.
