feat: add pharmacy-product linking system

- Add pharmacy_products table (PostgreSQL + SQLite)
- Add public route GET /api/products/:source/:id/pharmacies
- Add admin CRUD routes for pharmacy-product links
- Add cascade delete when pharmacy is removed
- Update ProductView to show linked pharmacies
- Create PharmacyProductLink admin component
- Add 'Vincular Producto a Farmacia' tab in AdminView

+# Parafarmacia + Productos de Bebé — Design Spec
+
+**Date:** 2026-07-13
+**Status:** Approved
+**Author:** MiMoCode
+
+## Problem
+
+FarmaFinder currently only searches medications via the CIMA API. Users need to find parapharmacy products (OTC medications, vitamins, topical treatments) and baby products (formula milk, baby food, cereals) — categories that pharmacies sell but CIMA doesn't cover comprehensively.
+
+## Goal
+
+Extend FarmaFinder's search to include:
+1. **OTC medications** from CIMA (filtered by `cpresc = "Sin Receta"`)
+2. **Baby products** (formula milk, baby food, cereals) from Open Food Facts API
+
+Results should appear in a unified search alongside existing prescription medication results.
+
+## Data Sources
+
+### CIMA API (existing, extended)
+
+- **Base URL:** `https://cima.aemps.es/cima/rest`
+- **No authentication required**
+- **New filter:** `cpresc=Sin+Receta` to get only OTC products
+- **Endpoints used:**
+  - `GET /medicamentos?nombre={query}&cpresc=Sin+Receta` — search OTC products
+  - `GET /medicamento/{nregistro}` — get OTC product details
+- **Rate limits:** None documented; existing 5s timeout per request
+- **Data fields:** nregistro, nombre, labtitular, cpresc, formaFarmaceutica, vtm, dosis, fotos, docs
+
+### Open Food Facts API (new)
+
+- **Base URL:** `https://world.openfoodfacts.org/api/v2`
+- **No authentication required**
+- **Endpoints used:**
+  - `GET /search?categories_tags=baby-food&search_terms={query}&json=true` — search baby products
+  - `GET /product/{barcode}.json` — get product details
+- **Rate limits:** Be polite (< 10 req/s)
+- **Data fields:** product_name, brands, image_url, nutriscore, ingredients_text, categories_tags
+- **Product categories to search:**
+  - `baby-foods` — general baby food
+  - `baby-milks` — formula milk
+  - `cereals-for-babies` — baby cereals
+  - `snacks-and-desserts-for-babies` — baby snacks
+
+## Architecture
+
+### Data Flow
+
+```
+User searches "leche"
+  → Frontend: GET /api/products/search?q=leche
+    → Backend orchestrator:
+      1. cimaService.searchOTC('leche')      — CIMA OTC search
+      2. offService.searchBaby('leche')       — Open Food Facts search
+      3. Merge results with source tag
+      4. Cache in Redis (1h TTL)
+    → Return unified result list
+```
+
+### Unified Product Model
+
+```typescript
+interface Product {
+  id: string;                    // nregistro (CIMA) or _id (OFF)
+  source: 'cima' | 'openfoodfacts';
+  name: string;
+  brand: string;                 // labtitular (CIMA) or brands (OFF)
+  category: 'otc' | 'baby_food' | 'baby_milk' | 'baby_cereal';
+  image_url: string | null;      // fotos[0].url (CIMA) or image_url (OFF)
+
+  // CIMA-specific fields
+  active_ingredient?: string;    // vtm.nombre
+  dosage?: string;               // dosis
+  form?: string;                 // formaFarmaceutica.nombre
+  prescription?: string;         // cpresc
+  commercialized?: boolean;      // comerc
+  photos?: string[];
+  docs?: { tipo: number; url: string }[];
+
+  // OFF-specific fields
+  nutriscore?: string;           // nutriscore_grade
+  ingredients?: string;          // ingredients_text
+  nova_group?: number;           // nova_group
+  eco_score?: string;            // ecoscore_grade
+}
+```
+
+## Backend Changes
+
+### 1. New file: `apps/backend/off-service.js`
+
+Open Food Facts API client:
+
+```javascript
+const OFF_API_BASE = 'https://world.openfoodfacts.org/api/v2';
+
+async function searchBabyProducts(query) {
+  // Search in baby-food categories
+  const url = `${OFF_API_BASE}/search?categories_tags=baby-food&search_terms=${encodeURIComponent(query)}&json=true&fields=product_name,brands,image_url,nutriscore_grade,ingredients_text,nova_group,ecoscore_grade,categories_tags&page_size=20`;
+  // Cache key: off:baby:{query}, TTL: 1 hour
+  // Transform to unified Product model
+}
+
+async function getBabyProductDetails(barcode) {
+  const url = `${OFF_API_BASE}/product/${barcode}.json`;
+  // Cache key: off:product:{barcode}, TTL: 24 hours
+  // Transform to unified Product model
+}
+```
+
+### 2. Modify: `apps/backend/cima-service.js`
+
+Add OTC-specific search function:
+
+```javascript
+async function searchOTC(query) {
+  // Same as searchMedicines but adds cpresc=Sin+Receta filter
+  // Cache key: cima:otc:{query}, TTL: 1 hour
+  // Transform to unified Product model (add source: 'cima', category: 'otc')
+}
+```
+
+### 3. Modify: `apps/backend/server.js`
+
+New unified search route:
+
+```javascript
+app.get('/api/products/search', async (req, res) => {
+  const { q } = req.query;
+  // Launch parallel searches:
+  const [cimaResults, offResults] = await Promise.allSettled([
+    searchOTC(q),
+    searchBabyProducts(q)
+  ]);
+  // Merge, deduplicate, sort by relevance
+  // Return unified results
+});
+
+app.get('/api/products/:source/:id', async (req, res) => {
+  const { source, id } = req.params;
+  if (source === 'cima') return getMedicineDetails(id);
+  if (source === 'openfoodfacts') return getBabyProductDetails(id);
+});
+```
+
+### 4. Redis Cache Strategy
+
+| Key Pattern | TTL | Source |
+|-------------|-----|--------|
+| `products:search:{query}` | 1 hour | Merged results |
+| `cima:otc:{query}` | 1 hour | CIMA OTC only |
+| `off:baby:{query}` | 1 hour | OFF baby only |
+| `off:product:{barcode}` | 24 hours | OFF product detail |
+
+## Frontend Changes
+
+### 1. New component: `ProductResults.jsx`
+
+Displays unified search results with:
+- Product card with image, name, brand
+- Source badge: "CIMA" or "Open Food Facts"
+- Category badge: "OTC", "Baby Food", "Formula"
+- Click navigates to `/product/{source}/{id}`
+
+### 2. Modify: `PublicView.jsx`
+
+- Update search to call `/api/products/search?q=`
+- Show unified results alongside existing medicine results
+- Add category filter tabs: "All" | "Medications" | "OTC" | "Baby"
+
+### 3. Modify: `MedicineResults.jsx`
+
+- Accept mixed product types
+- Conditionally render fields based on `source`
+- Show CIMA-specific fields (active ingredient, dosage) for CIMA products
+- Show OFF-specific fields (nutriscore, ingredients) for OFF products
+
+### 4. New route: `/product/:source/:id`
+
+- Detail page for any product type
+- CIMA products: show full medication info + pharmacies
+- OFF products: show nutritional info + "Available at pharmacies" section
+
+## Mobile Changes
+
+### 1. `apps/frontend-mobile/services/products.ts`
+
+```typescript
+export async function searchProducts(query: string): Promise<Product[]> {
+  const { data } = await api.get('/products/search', { params: { q: query } });
+  return data.results;
+}
+```
+
+### 2. `apps/frontend-mobile/app/(tabs)/search.tsx`
+
+- Add product search alongside medicine search
+- Display unified results with source/category badges
+
+### 3. `apps/frontend-mobile/app/product/[source]/[id].tsx`
+
+- New detail screen for non-medication products
+- Adapt layout based on product source
+
+## Error Handling
+
+- CIMA API down: return OFF results only (graceful degradation)
+- OFF API down: return CIMA results only
+- Both down: return cached results if available, else empty
+- OFF rate limit: implement 100ms delay between requests
+
+## Testing
+
+1. **Unit tests:** off-service.js search/transform functions
+2. **Integration tests:** `/api/products/search` endpoint with mocked APIs
+3. **Manual test:** Search "leche" and verify both CIMA OTC + OFF baby results appear
+4. **Edge cases:** Empty results, API timeout, malformed OFF responses
+
+## Out of Scope
+
+- Homeopathy (not reliably available in either API)
+- Commercial parapharmacy APIs (paid, not needed for OTC + baby)
+- Product price/stock for OFF products (pharmacies don't stock these in the current model)
+- User reviews/ratings for products
