feat(01-05): super-admin UI panel and comprehensive test harness

- (super-admin)/layout.tsx: server guard (isSuperAdmin check), sidebar nav - (super-admin)/admin/page.tsx: dashboard with tenant stats (total/active/suspended) - (super-admin)/admin/tenants/page.tsx: tenant table with status badges, suspend/activate - src/middleware.ts: /admin/* routes require isSuperAdmin in JWT token - src/lib/__tests__/super-admin.test.ts: 11 tests covering middleware guard + suspension logic - All 93 tests pass (auth 8, RBAC 66, isolation 6, super-admin 11, setup 2) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

+/**
+ * Super-Admin Unit Tests
+ *
+ * Tests for the withSuperAdmin() middleware guard and tenant suspend/activate logic.
+ *
+ * These tests mock the auth layer (getCurrentUser) and the Prisma layer,
+ * so they do NOT require a live database connection.
+ *
+ * WHAT IS TESTED:
+ * - withSuperAdmin allows super-admin users through
+ * - withSuperAdmin returns 401 when no session exists
+ * - withSuperAdmin returns 403 when authenticated user is not super-admin
+ * - Tenant suspension sets PENDING_SUSPENSION status with grace period dates
+ * - Tenant activation sets ACTIVE status and clears suspension fields
