docs(03): plan Phase 3 — Service Catalog & Quote Builder (4 plans, 2 waves)

Wave 1: schema push (service_id nullable + custom_label).
Wave 2 (parallel): catalog CRUD page + quote builder tab.
Wave 3: E2E human verification checkpoint.

truths:
- "Admin can navigate to /admin/catalog from the NavBar ('Catalogo' link visible between Statistiche and Esci)"
- "Admin can see a table of all services with columns Nome | Descrizione | Prezzo | Stato | Azioni"
- "Admin can add a new service via an inline form (name, optional description, unit price) — it appears in the table after save"
- "Admin can click 'Modifica' on a row and edit name, description, price inline — changes persist after save"
- "Admin can click 'Disattiva' to soft-delete a service (active=false) — row shows 'Disattivato' badge at 50% opacity"
- "Admin can click 'Riattiva' on a disabled service to re-enable it"
- "Inactive services remain visible in the table (with badge) but are excluded from the quote builder dropdown"

<objective>
Deliver the complete `/admin/catalog` page: NavBar link, page layout, table with inline edit, add-service form, and soft-delete toggle. This is a self-contained vertical slice — after this plan executes, the admin can manage the service catalog end-to-end.
Purpose: Fulfills CAT-01 (service database with prices). Provides the catalog data that Wave 2's Quote Builder (plan 03-03) will query for its dropdown.
Output: 5 new/modified files — a fully functional service catalog page.

**Create `src/app/admin/catalog/actions.ts`** — three Server Actions following exact Zod+FormData pattern from `clients/[id]/actions.ts`:
```typescript
"use server";
import { db } from "@/db";
import { service_catalog } from "@/db/schema";
import { revalidatePath } from "next/cache";
import { eq } from "drizzle-orm";
import { z } from "zod";

description: formData.get("description") ?? "",
unit_price: formData.get("unit_price"),

await db.insert(service_catalog).values({

description: formData.get("description") ?? "",
unit_price: formData.get("unit_price"),

await requireAdmin();
await db
.update(service_catalog)
.set({ active })
.where(eq(service_catalog.id, serviceId));
revalidatePath("/admin/catalog");
}
```
**Add `getAllServices()` to `src/lib/admin-queries.ts`** — append at end of file before the closing exports:
```typescript
export async function getAllServices(): Promise<ServiceCatalog[]> {
return db
.select()
.from(service_catalog)
.orderBy(asc(service_catalog.name));
}
```
Also add `service_catalog` to the imports at top of admin-queries.ts, and `ServiceCatalog` to the type imports. Add `asc` if not already imported from `drizzle-orm`.

## Trust Boundaries
| Boundary | Description |
|----------|-------------|
| Admin browser → Server Actions (catalog/actions.ts) | FormData from admin form crosses to server; must be validated before DB write |
| /admin/catalog route → Auth.js session | All catalog routes inherit the `/admin/*` middleware session check from Phase 2; no additional guard needed at page level |
## STRIDE Threat Register
| Threat ID | Category | Component | Disposition | Mitigation Plan |
|-----------|----------|-----------|-------------|-----------------|
| T-03-02-01 | Spoofing | createService / updateService / toggleServiceActive | mitigate | `requireAdmin()` calls `getServerSession(authOptions)` at the top of every Server Action — rejects if no valid session |
| T-03-02-02 | Tampering | serviceSchema Zod validation | mitigate | `unit_price` validated as `z.coerce.number().min(0.01)` — prevents zero/negative prices; `name` requires min length 1 |
| T-03-02-03 | Tampering | updateService serviceId parameter | mitigate | serviceId is bound at call site in the Server Action closure — admin can only modify the row ID passed from the server-rendered page |
| T-03-02-04 | Information Disclosure | /admin/catalog page | accept | Page is behind Auth.js `/admin/*` middleware (enforced in Phase 2); service prices are admin-internal data, not client-facing |
| T-03-02-05 | Tampering | XSS in service name / description | accept | React JSX auto-escapes all string output; no `dangerouslySetInnerHTML` used; UI-SPEC forbids it |
</threat_model>

After both tasks complete:
1. `grep '/admin/catalog' src/components/admin/NavBar.tsx` returns 1 match
2. `npx tsc --noEmit` exits clean
3. `npm run build` succeeds
4. Navigating to `/admin/catalog` (dev server) shows the catalog page with table headers and "Aggiungi servizio" button
5. Adding a service via the form makes it appear in the table
6. Clicking "Disattiva" changes badge to "Disattivato" and reduces row opacity
</verification>
<success_criteria>
- `/admin/catalog` route is accessible from NavBar and renders without error
- All three Server Actions (createService, updateService, toggleServiceActive) are exported from `catalog/actions.ts` with Zod validation and `requireAdmin()` guard
- ServiceTable renders per-row inline edit using the DocumentRow pattern
- Inactive services show "Disattivato" badge; active services show "Attivo" badge
- TypeScript and build both pass clean
</success_criteria>
