Move the settings screen to its own top-level menu 
Adds an "M365 Login" menu entry with a Microsoft-style icon and one
submenu per tab (Connection, Button, Security). The active tab is taken
from the URL, kept in the post-save redirect and highlighted in the
submenu. Notices are printed explicitly because top-level pages do not
include options-head.php. Links, docs and screenshots updated.

[1.0.0] – 2026-09-22

Added

  • "Sign in with Microsoft" button on wp-login.php (OpenID Connect authorization code flow with PKCE).
  • Matching of existing WordPress users by e-mail address (optional UPN fallback), no user provisioning.
  • Settings screen (own top-level menu entry "M365 Login") with connection, button and security tabs, live button preview, colour presets, media-library icon picker, redirect-URI copy button and tenant connectivity test.
  • ID token verification against Microsoft's JWKS (RS256, issuer, audience, tenant, expiry, nonce).
  • Encrypted client secret storage (AES-256-GCM).
  • Certificate based client authentication (RFC 7523 private_key_jwt): one-click generation of a 3072-bit RSA key pair with self-signed certificate, .cer download, own PEM upload, expiry display; step-by-step guides for both methods in the settings.
  • Security audit (docs/security-audit.md) with fixes: unverified email claim ignored in multi-tenant mode, login-start rate limit, trusted proxy IP header.
  • Account binding to the Microsoft object ID, e-mail domain allow-list.
  • Entra group restriction with a Graph-powered group picker; membership verified via the groups claim or Microsoft Graph checkMemberGroups.
  • Button-only mode that hides the password form and blocks password sign-in on wp-login.php, with a secret, rate-limited fallback link and a wp-config.php emergency constant.
  • Custom login page support: automatic button in wp_login_form() forms, m365_login_button() / m365_login_messages() template functions, custom login URL for error messages, fallback link and logout redirect.
  • [m365_login_button] shortcode (with divider and messages attributes) and developer hooks.
  • German translation.
