Adds a WordPress plugin that places a customisable "Sign in with Microsoft" button on wp-login.php and signs existing users in via the OpenID Connect authorization code flow with PKCE. Users are matched by e-mail address only; no accounts are created. Security: single-use state/nonce bound to an HttpOnly cookie, ID token signature verification against Microsoft's JWKS (RS256 only) with issuer/audience/tenant/expiry/nonce checks, optional tenant pinning, account binding to the Microsoft object ID, e-mail domain allow-list, client secret encrypted at rest (AES-256-GCM). Admin: settings screen with connection, button and security tabs, live button preview, colour presets, media-library icon picker, redirect URI copy button and tenant connectivity test. Packaging for WordPress.org: readme.txt with External services section, GPL-2.0 license, uninstall.php, POT + German translations, .distignore, build script, PHPCS config and CI running Plugin Check.
