New page at /admin/system-info with three tabs:
- Overview: PHP version, SAPI, environment, 6 health checks (DB, schema,
storage, RBAC baseline, admin role, scheduler heartbeat)
- Modules: table of active modules with version, dependencies, permission count
- Permissions: active/inactive counts and per-source breakdown
Gated behind new system_info.view permission assigned to Admin role.
No mutations — purely diagnostic/observability.
Includes SystemHealthService, SystemInfoService, SystemHealthRepository
with interface, DI registration, i18n keys (de+en), idempotent DB update
script, and 17 new PHPUnit tests.

When a session expires, the user's current URL is now captured and restored
after re-authentication (via remember-me cookie or manual login), instead of
always redirecting to the dashboard. A JavaScript session warning dialog
appears ~2 minutes before idle timeout, allowing users to extend their session
with a single click. Includes open-redirect prevention via URL validation,
Microsoft SSO callback support, and 33 unit tests.
