Drop the CI badge pointing at a non-existent GitHub repo and darken the
PHP and Plugin Check badge colours for sufficient contrast with white text.

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.

Add certificate authentication, in-app setup guides and security audit
Certificate (RFC 7523 client assertion) as an alternative to the client
secret: one-click generation of a 3072-bit RSA key pair with a
self-signed certificate, .cer download (public part only), own PEM
upload with validation, expiry display, encrypted key storage. Both the
authorization code exchange and the Graph client-credentials request
use the selected method. Step-by-step guides for secret, certificate
and the app registration are shown in the settings.

Security audit (docs/security-audit.md) and fixes:
- Multi-tenant mode ignored the unverified email claim: matching now
  uses the UPN only, or the email claim when xms_edov is true.
- Login starts are rate limited per client (30 per 10 minutes).
- Optional trusted proxy header for client IPs
  (M365_LOGIN_CLIENT_IP_HEADER / filter).

Use flex divider lines on custom login pages
The absolute line behind the divider text needs a known background;
on themed pages the text now sits between two flex lines instead.

Support custom login pages
- Add the button (and error messages) to every wp_login_form() form via
  login_form_top/login_form_bottom; in button-only mode the password
  fields are wrapped and hidden there.
- New template functions m365_login_button() and m365_login_messages();
  the shortcode gains divider and messages attributes.
- New setting for the custom login page URL: failed sign-ins, the
  fallback link and the logout redirect point there instead of
  wp-login.php. Must be a same-site URL.
- Button-only mode now blocks every interactive password sign-in
  through the authenticate filter, not only wp-login.php; XML-RPC, REST,
  WP-CLI and cron are exempt, plus a filter for trusted exceptions.
- Fallback key accepted on any page (init) instead of login_init only.

Add rendered preview screenshots to the README
Login page (default and button-only mode) and the three settings tabs,
rendered from the plugin's own markup and CSS inside a mock WordPress
admin shell.

Add Entra group restriction, button-only mode and detailed README
Groups: a Graph-backed picker on the Security tab (search by name or
paste object IDs) stores allowed group IDs. During sign-in membership is
read from the ID token's groups claim when present, otherwise verified
through Microsoft Graph checkMemberGroups (transitive). Verification
failures refuse the sign-in.

Button-only mode: hides the password form and the lost-password link
and rejects password sign-ins on wp-login.php via the authenticate
filter. A generated, rate-limited fallback key re-enables the form for
30 minutes per browser; M365_LOGIN_DISABLE_BUTTON_ONLY switches the
mode off from wp-config.php.

Also: new German-language README with sequence diagram, settings
reference, troubleshooting and hook examples; readme.txt external
services section now covers Microsoft Graph; translations updated.

Build ZIP with tar instead of rsync
rsync is not available everywhere; tar honours the same .distignore
patterns and ships with every CI runner.

Add M365 Login plugin: Microsoft Entra ID sign-in for existing users
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.
