fix(nginx): fix invalid if add_header directive and dynamic backend host

- TASK-FIN-001: Eliminate N+1 query loop in OrdersService.create with batched findMany query.
- Perform monetary calculations strictly using Prisma.Decimal methods (.add(), .mul(), .sub()).
- Add validation for duplicate product IDs and invalid quantities in order items.
- Implement global DecimalInterceptor registered in main.ts to serialize Prisma.Decimal values into exact string representations in API responses.
- TASK-SEC-003: Create roles.decorator.ts and roles.guard.ts in common directory with backward-compatible re-exports in auth directory.
- Enforce RBAC on SettingsController with @UseGuards(JwtAuthGuard, RolesGuard) and @Roles('Admin').
- Add unit specs for DecimalInterceptor, RolesGuard, SettingsController, and OrdersService Decimal batch operations.

+- **Description**: RESTful API supporting authentication, users, pets, products, orders, wallet transactions, and administrative settings.
+
+### 3. Excluded Placeholder / Non-Auditable Directories
+- **`frontend/application`**: NON-AUDITABLE / GENERATED PLACEHOLDER. Contains build/cache artifacts (`.next/`, `tsconfig.tsbuildinfo`, `next-env.d.ts`, `node_modules/`). Lacks root `package.json` or source code files (`src/` or `app/`). **EXCLUDED FROM SOURCE AUDIT.**
+- **`frontend/admin-panel`**: NON-AUDITABLE PLACEHOLDER. Contains only `node_modules/` directory without `package.json` or source files. **EXCLUDED FROM SOURCE AUDIT.**
+
+---
+
+## Mandatory Global Audit Exclusions
+All Phase 2 auditors must strictly ignore generated code, build output, dependencies, and temporary caches:
+- `**/node_modules/**`
+- `**/.next/**`
+- `**/dist/**`
+- `**/build/**`
+- `**/coverage/**`
+- `**/.turbo/**`

+# System Discovery
+
+## Current Architecture
+The Canino Iran system is structured around an active customer storefront and a NestJS REST API backend.
+
+### Active Core Applications
+1. **React / Vite Storefront Application** (`src/`): React 19 + Vite 6 Single Page Application for customer product discovery, supplement dosage recommendation, pet registration, health tracking, and wallet management.
+2. **NestJS Backend Service** (`backend/src/`): Modular NestJS 11 backend service providing business logic, authentication, pet data, catalog management, orders, and system settings.
+3. **Database Layer**: PostgreSQL database modeled via Prisma ORM 5.22 (`backend/prisma/schema.prisma`).
+4. **Caching & Session Layer**: Redis via `ioredis` for throttling, caching, and session storage.
+
+### Excluded / Non-Auditable Artifacts
+1. **`frontend/application`**: Next.js build/cache placeholder containing only `.next/`, `tsconfig.tsbuildinfo`, `next-env.d.ts`, and `node_modules/`. Lacks an active `package.json` or source tree. Excluded from code audit.
+2. **`frontend/admin-panel`**: Placeholder directory containing only `node_modules/`. Excluded from code audit.
+
+---
+
+## Major Business Domains Discovered
+- **User & Wallet Domain**: User profile, authentication (JWT), multi-address support, wallet deposit/withdrawal ledger.
+- **Pet & Health Domain**: Pet registration, breed/weight profiling, medical conditions tracking, daily health logs, dosing reminders.
+- **Product & Dosage Domain**: Supplement catalog, dosage logic calculation based on pet weight and species, category listings, ingredient/symptom mapping.
+- **Order & Charity Domain**: Checkout workflow, coupon validation, tracking numbers, automatic charity donation allocations.
+- **Settings & Content Domain**: Administrative UI text updates and scientific glossary definitions.
+
+---
+
+## Technical Architecture Summary
+
+- **Authentication / Authorization**: JWT tokens issued via NestJS Passport strategy (`backend/src/auth`). Supported roles in schema: `User_PetOwner` and `Admin`.
+- **API Architecture**: REST endpoints documented via NestJS Swagger OpenAPI (`backend/src/main.ts`) and root `swagger.yml`.
+- **Database & Migration**: PostgreSQL managed by Prisma ORM (`backend/prisma/schema.prisma`).
+- **Container Infrastructure**: Multi-stage Dockerfiles and `docker-compose.yml` for `frontend`, `backend`, `postgres`, `redis`, `nginx`, and `prometheus`.

+## Evidence-Based Status Matrix
+
+| Component / Finding | Classification | Supporting Evidence |
+| :--- | :--- | :--- |
+| Root Storefront App (React 19 + Vite 6) | Active Application | `package.json`, `vite.config.ts`, `src/App.tsx` |
+| NestJS Backend Service | Active Application | `backend/package.json`, `backend/prisma/schema.prisma`, `backend/src/main.ts` |
+| PostgreSQL & Prisma ORM Layer | Active Database Layer | `backend/prisma/schema.prisma`, `backend/package.json` |
+| Redis In-Memory Store | Active Cache/Throttle | `backend/src/redis/`, `backend/package.json` |
+| Docker Compose Environment | Active Infrastructure | `docker-compose.yml`, `Dockerfile`, `backend/Dockerfile` |
+| `frontend/application` | Excluded Placeholder | Lacks `package.json` and `src/`. Contains only build artifacts (`.next/`, `next-env.d.ts`). |
+| `frontend/admin-panel` | Excluded Placeholder | Lacks `package.json` and `src/`. Contains only `node_modules/`. |
+| Standalone Admin Panel App | Non-Existent | No source tree found in `frontend/admin-panel` or `src/components/Admin*`. Admin API capabilities exist in backend (`backend/src/settings`). |
+| Live Payment Gateway Integration | Inferred / Unknown | Frontend relies on mock checkout; schema supports transactions. |
+| Automated CI/CD Pipelines | Missing / Unknown | No `.github/workflows` or equivalent discovered. |
