Help wanted: validate a React document metadata review SPFx sample

A new read-only React sample is ready for the PnP SharePoint Framework webparts repository:

• Pull request: https://github.com/pnp/sp-dev-fx-webparts/pull/6482
• Sample: samples/react-document-metadata-review/

The web part reviews a bounded SharePoint document-library or folder view and highlights missing or invalid metadata. It supports required text, choice, and taxonomy field checks, then provides safe links for people to remediate the source documents.

It deliberately performs no create, update, or delete operations. The README documents the SharePoint permissions, configuration format, and tenant validation steps.

Local verification completed:

• 13 deterministic Jest tests passed.
• SPFx DEBUG and SHIP builds passed.
• Production .sppkg packaging passed.
• Scope and security review found no secrets or unrelated changes.

Could someone with a SharePoint Online tenant please test this against a representative document library and report back on the PR? Useful checks include metadata highlighting, folder scoping, taxonomy values, permission-denied and throttling behavior, safe links, keyboard access, and responsive layout. Real tenant screenshots would be especially helpful; none are fabricated here.

Thank you for helping validate and improve this community sample.
