test(frontend): add provider admin acceptance coverage

Add a dedicated acceptance script for providers.html, cover it in the local real-host script regression suite, and document the current frontend review baseline, closure audit, providers action matrix, and remediation task board.

This keeps the frontend acceptance boundary explicit: providers.html now has a repeatable verification entry point for its page-level actions, while non-UI provider operations remain documented as backend-only capabilities.
