refactor: substitui backend Medusa por backend Go e corrige testes do marketplace

Browse source 
- Remove backend Medusa.js (TypeScript) e substitui pelo backend Go (saveinmed-performance-core)
- Corrige testes auth.test.ts: alinha paths de API (v1/ sem barra inicial) e campo access_token
- Corrige GroupedProductCard.test.tsx: ajusta distância formatada (toFixed) e troca userEvent por fireEvent com fakeTimers
- Corrige AuthContext.test.tsx: usa vi.hoisted() para mocks e corrige parênteses no waitFor

## 🧪 Cobertura de Testes
| Pacote | Cobertura |
|--------|-----------|
| `config` | **100%** ✅ |
| `middleware` | **95.9%-100%** ✅ |
| `payments` | **100%** ✅ |
| `usecase` | **64.7%-88%** |
| `server` | **74.7%** |
| `handler` | 6.6%-50% |
## 🔧 Configuração
### Variáveis de Ambiente
```bash
# Banco de Dados
DATABASE_URL=postgres://user:password@localhost:5432/saveinmed?sslmode=disable
# Servidor
BACKEND_PORT=8214
# Autenticação
JWT_SECRET=your-secret-key
JWT_EXPIRES_IN=24h
PASSWORD_PEPPER=your-pepper
# Admin Seeding (criado automaticamente na inicialização)
ADMIN_NAME=Administrator
ADMIN_USERNAME=admin
ADMIN_EMAIL=admin@saveinmed.com
ADMIN_PASSWORD=admin123
# CORS
CORS_ORIGINS=*
# Mercado Pago
MERCADOPAGO_BASE_URL=https://api.mercadopago.com
MARKETPLACE_COMMISSION=2.5
```
### Autenticação
A autenticação utiliza **username** (não email) para login:
```json
POST /api/v1/auth/login
{
"username": "admin",
"password": "admin123"
}
```
### Pré-requisitos
- Go 1.24 ou superior
- PostgreSQL 14+
- Swag CLI (para regenerar documentação)
## 🏃 Execução Local
```bash
# Configurar variável de ambiente
export DATABASE_URL=postgres://postgres:postgres@localhost:5432/saveinmed?sslmode=disable
# Instalar dependências
go mod download
# Executar API
go run ./cmd/api
# API estará disponível em http://localhost:8080
# Swagger UI em http://localhost:8080/docs/index.html
```
## 🐳 Docker
```bash
# Build da imagem
docker build -t saveinmed-api:latest .
# Executar container
docker run -p 8080:8080 \
-e DATABASE_URL=postgres://user:password@host:5432/saveinmed \
saveinmed-api:latest
```
## 📚 Documentação da API
A documentação completa da API está disponível via Swagger UI:
```
http://localhost:8080/docs/index.html
```
### Regenerar Swagger
```bash
# Instalar swag
go install github.com/swaggo/swag/cmd/swag@latest
# Gerar documentação
swag init --dir ./cmd/api,./internal/http/handler,./internal/domain \
--output ./docs \
--parseDependency \
--parseInternal
```
## 🧪 Testes
```bash
# Executar todos os testes
go test ./...
# Executar testes com coverage
go test -cover ./...
# Gerar relatório de coverage
go test -coverprofile=coverage.out ./...
go tool cover -html=coverage.out
```
> Para matriz completa (com/sem banco e Playwright), veja: [docs/TESTES.md](../docs/TESTES.md)
## 📊 Performance
Esta API foi otimizada para alta performance:
- **json-iterator**: ~2-3x mais rápido que encoding/json padrão
- **Compressão gzip**: Reduz tamanho das respostas em ~70%
- **Connection pooling**: Gerenciamento eficiente de conexões com PostgreSQL
- **Prepared statements**: Queries otimizadas e protegidas contra SQL injection
## 🔗 Integração com Outros Componentes
- **Backoffice (NestJS)**: Compartilha o mesmo banco de dados PostgreSQL
- **Marketplace Frontend**: Consome esta API para operações críticas
- **SaveInMed BFF**: Pode fazer proxy para endpoints específicos desta API
## 📝 Licença

## Getting Started
Visit the [Quickstart Guide](https://docs.medusajs.com/learn/installation) to set up a server.
This service handles the core business logic, data persistence, and external integrations for the SaveInMed B2B Marketplace.
Visit the [Docs](https://docs.medusajs.com/learn/installation#get-started) to learn more about our system requirements.
## 🏗 Architecture
## What is Medusa
The backend follows a layered architecture to ensure separation of concerns and maintainability.
Medusa is a set of commerce modules and tools that allow you to build rich, reliable, and performant commerce applications without reinventing core commerce logic. The modules can be customized and used to build advanced ecommerce stores, marketplaces, or any product that needs foundational commerce primitives. All modules are open-source and freely available on npm.

# Roteiro de Prompts para o Gemini CLI
## Status (pronto x faltando)
**Pronto**
- Conteúdo descrito neste documento.
**Faltando**
- Confirmar no código o estado real das funcionalidades e atualizar esta seção conforme necessário.
---
Este roteiro sequencial ajuda a guiar o Gemini CLI na construção dos componentes críticos do marketplace B2B farmacêutico `saveinmed-performance-core`, garantindo que o contexto de logística com rastreabilidade e a stack Go + PostgreSQL sejam respeitados.
## Parte 1 — Contexto e Infraestrutura de Banco (Migrations)
Atue como um **Arquiteto de Software Especialista em Marketplaces B2B**. O projeto é o `saveinmed-performance-core`, focado em logística farmacêutica com rastreabilidade. Stack: **Go** (puro ou com Echo/Gin) e **PostgreSQL**.
Gere o **SQL de migration** inicial contendo as tabelas:
- `users` (id, nome, email, senha_hash, role: admin/seller/buyer, company_id).
- `addresses` (vinculado a empresas e usuários).
- `inventory` (vinculado a produtos, com lote, validade e quantidade disponível).
- `cart_items` (para persistência de carrinho).
- `audit_logs` (para rastreabilidade de alterações em pedidos/lotes).
Mantenha as chaves estrangeiras com as tabelas `companies` e `products` já existentes no print do Swagger.
## Parte 2 — Autenticação e Autorização (JWT + RBAC)
Com base nas tabelas criadas, implemente em Go o módulo de **Autenticação v1**:
- **POST `/api/v1/auth/register`**: suporte para criação de usuário vinculado a uma empresa.
- **POST `/api/v1/auth/login`**: retorna **JWT** com claims de `Role` e `CompanyID`.
- **Middleware de Auth** que valida o token e verifica permissões (**RBAC**).
Use `golang.org/x/crypto/bcrypt` para o hashing de senhas.

# Integration Tests
The `medusa-test-utils` package provides utility functions to create integration tests for your API routes and workflows.
For example:
```ts
import { medusaIntegrationTestRunner } from "medusa-test-utils"
medusaIntegrationTestRunner({
testSuite: ({ api, getContainer }) => {
describe("Custom endpoints", () => {
describe("GET /store/custom", () => {
it("returns correct message", async () => {
const response = await api.get(
`/store/custom`
)
expect(response.status).toEqual(200)
expect(response.data).toHaveProperty("message")
expect(response.data.message).toEqual("Hello, World!")
})
})
})
}
})
```
Learn more in [this documentation](https://docs.medusajs.com/learn/debugging-and-testing/testing-tools/integration-tests).
