(playwright) Stabilize Teams Hierarchy spec and replace toast-based team deletion checks

[harsh-vador]

Describe your changes:

Summary

This PR improves Playwright test reliability by tightening search export coverage and replacing a toast-only team deletion assertion with a real UI validation.

Changes

• Stabilized SearchExport.spec.ts to rely on real page behavior for export count validation
• Added end-to-end coverage for:
  • visible export count matching the first tab count
  • filtered result count matching exported CSV row count
  • browse/search export row count validation
• Tightened waitForResponse usage to only resolve on successful 200 search responses
• Isolated the > 200k assets export-limit behavior into a standalone mocked test
• Replaced the toast assertion in TeamsHierarchy.spec.ts after team deletion with a stronger check:
  • search for the deleted team
  • assert no results are returned

Type of change:

• Bug fix
• Improvement
• New feature
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation

Checklist:

• I have read the CONTRIBUTING document.
• My PR title is Fixes <issue-number>: <short explanation>
• I have commented on my code, particularly in hard-to-understand areas.
• For JSON Schema changes: I updated the migration scripts or explained why it is not needed.
