Surface backend validation error messages inline in the Create-API wizard

What

When validate-openapi rejects a definition by URL or file (HTTP 400 with a reason in the response body), the Create-API wizard's .catch handlers dropped the backend reason to console.error and showed only a generic "validation failed" message — the Validation Errors card stayed empty. A 400 was thus surfaced less prominently than a 200 isValid:false, which renders the backend errors in the card.

Change

• Add getValidationErrorsFromError() to thread the backend response.body.description into setValidationErrors() across the URL and file (API + MCP) rejection paths, so a rejected validation shows as prominently as the isValid:false path.
• Clear stale validation errors on file-validation success.
• Errors without a backend description return [] and keep the existing generic-message fallback.
• Adds a unit test for the helper.

Testing

validationErrorUtils jest suite (2/2 passing) + full publisher portal build green against feature_nw_access_control.

Notes

• Targets the feature_nw_access_control integration branch.

This repetition comes from a few added lines landing inside the pre-existing API/MCP/URL validation handlers
