feat(license): EnsureActiveLicense full implementation + license/dashboard routes

- EnsureActiveLicense: full child-role check via licenseAssignments().isActive()
- License model: add isActive() method, fix fillable order, expires_at cast to date
- LicenseFactory: active/expired/inactive states
- routes/web.php: /dashboard with auth+license middleware, /lizenz-abgelaufen
- tests: EnsureActiveLicenseTest (3 tests — block/allow/teacher bypass)
