Add Entra group restriction, button-only mode and detailed README

Browse source 
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.
