BSM Magic Login v1.0.41

- Rebuilt Overview with live KPI cards and one embedded daily analytics chart. Removed redundant Analytics submenu and redirected its old URL to Overview.
- Moved Microsoft Entra SSO to Login Methods > Single Sign-On. Added separate accordions for Microsoft Entra ID (working backend) and planned Google Workspace, Okta, Sign in with Google, and Sign in with Facebook (clearly Coming Soon; not enabled).
- Moved SMS providers ahead of SMS settings; SMS settings remain hidden when no enabled provider exists. Collapsed provider editor under Add SMS Provider; Save Provider uses the existing secure backend.
- Kept existing settings, database tables, credentials, and authentication endpoints; legacy admin URLs redirect to their new tabs.

Validation: PHP syntax, JavaScript syntax, ZIP integrity. Live WordPress browser and authentication testing remain pending.
