improvement(ui): share knowledge filter headings

[BillLeoutsakosvl346]

Summary

• Share the headings and conditional clear actions for Connectors, Content and Owner filters.
• Keep selection menus, empty-selection mappings and reset handlers unchanged.

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.
• Before/after browser fixtures cover the changed component's styling and interactions. Original and extracted controls have matching computed styles. 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)

Confidence Score: 5/5

The PR appears safe to merge because the extraction preserves existing filter behavior and introduces no actionable issues.

Summary

Extracts the repeated Connectors, Content, and Owner filter headings into a shared KnowledgeFilterHeading component while preserving filter state and reset behavior.

• Exports and consumes the component through the existing knowledge-components barrel.
• Updates the knowledge test mock to retain the extracted heading while stubbing unrelated components.

Before / after visual comparison

Knowledge filter headings share their label and Clear-action layout.

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.
