fix(search): align landing layout and history rows with Home

[waleedlatif1]

Summary

• Align Search with Home through one shared landing layout; keep history below the composer without shifting its position.
• Match recently viewed titles and rows to recent-search chips using existing EMCN typography and geometry.
• Replace the pending search spinner with the workspace chat Stop control, wired to query cancellation even after editing or clearing the draft.

Type of Change

• Bug fix

Testing

• 180 tests across 23 files, including a cancellation regression demonstrated failing before the fix.
• Type-check and lint-check across 26 workspaces; all 51 audits; block registry and generated artifact checks.
• All nine cleanup passes. Local browser comparison in light/dark, narrow and short layouts, long input, history switching, keyboard actions, and busy state. Heading/input positions match with zero history-tab layout shift.

Checklist

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

[Medium risk] Refactors landing page layout and search UI components.

The PR appears safe to merge; no new actionable issue or outstanding previous finding was identified.

Summary

The PR shares the Home landing layout with Search, aligns history and source-row styling, and replaces the pending spinner with a Stop control. Since the previous review, it keeps Stop available when the draft changes or is cleared and updates the cancellation regression test.
