Ho Ngoc Hai b81c6ac176 fix(pos): prevent duplicate orders by checking payment API result
ConfirmPayment() previously ignored PayOrderAsync return value and
always showed success screen, even when payment API returned 500.
This caused users to unknowingly create duplicate orders — one unpaid
(Validated) and one paid (Completed).

Root causes fixed:
- Pass amountTendered to PayOrderWithDetailsAsync (required by
  PayOrderCommandValidator for cash payments)
- Check payment API response before showing success screen
- Show error message with retry option when payment fails
- Add loading state to prevent double-clicks during processing

Affects: CafeDesktop, CafeMobile, CafeTablet, RestaurantDesktop

Quick Start

Prerequisites

  • Docker & Docker Compose
  • .NET 10.0 SDK
  • Node.js 25+
  • pnpm 8+

Run Locally

# Start infrastructure (PostgreSQL, Redis, RabbitMQ, MinIO, Traefik) + all services
cd deployments/local
docker compose up -d

# Run database migrations (per service)
./scripts/db/migrate.sh

# Start a specific service for development
./scripts/dev/start-service.sh iam-service-net

Architecture

Each .NET service follows Clean Architecture + CQRS:

ServiceName/
  src/
    ServiceName.API/              # Controllers + MediatR Commands/Queries
    ServiceName.Domain/           # Entities, aggregates, domain events (no dependencies)
    ServiceName.Infrastructure/   # EF Core, repositories, migrations
  tests/
    ServiceName.UnitTests/        # xUnit + FluentAssertions
    ServiceName.FunctionalTests/  # WebApplicationFactory integration tests
