Pull request overview

This PR modernizes FOSSE’s WordPress admin UI (Settings, Status, providers, and onboarding wizard) by introducing shared “Gutenberg-like” UI primitives (cards, fields, badges, detail lists, callouts, action bars) and updating markup/tests to match.

Changes:

• Reworks admin screen markup to use shared card/field/detail-list primitives while preserving existing actions/nonces/targets.
• Updates onboarding wizard step layouts (including completion messaging/actions) to use consistent card surfaces.
• Refreshes PHPUnit + Playwright contracts to assert the new classnames/structure and visual/layout invariants.
