improvement(ui): share table sidebar headers

[BillLeoutsakosvl346]

Summary

• Share the header layout and action buttons across column, enrichment and workflow configuration sidebars.
• Preserve all five headers' title markup, overflow, spacing, icons and callbacks. Reuse EMCN Button without adding a new variant; add the existing keyboard-only focus treatment.

Type of Change

• Improvement

Testing

• All workspace type checks, lint, import/API validation and required repository audits pass; 21 existing consumer tests pass.
• Source comparison accounts for five headers and seven actions and confirms the remaining caller logic is unchanged.
• Browser fixture checked in light/dark themes, including long titles, close/back callbacks and keyboard activation.
• Committed design check completed with four retained warnings in the shared action: the existing 28px geometry and three keyboard-focus styling declarations. These are deliberate product-level composition choices; changing geometry or adding a global variant would broaden this extraction. No checker rules were changed.

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; the extraction preserves the existing header structure and action behavior.

Summary

This PR consolidates five table-sidebar headers and seven close/back actions into shared components while preserving each consumer’s title, overflow, layout, and callback behavior.

• Adds TableSidebarHeader as the canonical container for table configuration sidebar headers.
• Adds TableSidebarHeaderAction around the existing EMCN Button configuration with a keyboard-visible focus treatment.
• Migrates column, enrichment, and workflow sidebar headers without changing their underlying configuration logic.
