Migrate UAT environment from PostgreSQL to MySQL

[Copilot]

Replaces PostgreSQL dependencies with MySQL for the UAT runtime environment and adds MySQL service to docker-compose orchestration.

Changes

Dockerfile

• runtime-uat stage: Replaced postgresql-client with default-mysql-client

pyproject.toml

• UAT dependency group: Replaced psycopg2-binary with mysqlclient==2.2.7

docker-compose.yml

• Added mysql:8.0 service with:
  • Health check using application credentials
  • Named volume for data persistence
  • Configurable ports and credentials via environment variables
• Updated parts_webapi service:
  • Added depends_on with health check condition
  • Set MySQL defaults: DB_HOST=mysql, DB_PORT=3306, DB_ENGINE=django.db.backends.mysql

Configuration

Requires these environment variables:

• DB_NAME, DB_USER, DB_PASSWORD - MySQL application credentials
• DB_ROOT_PASSWORD - Optional, defaults to "rootpassword"
• MYSQL_CONTAINER_NAME, MYSQL_PORT - Optional overrides

Original prompt
