feat: add middleware client tools (MySQL, PostgreSQL, Redis, Docker, Kafka CLI)

Add commonly used database and middleware client tools for development convenience:
- PostgreSQL client 17 (psql)
- Docker CLI with buildx and compose plugins
- MySQL client (default-mysql-client)
- Redis CLI (redis-tools)
- Kafka CLI 3.9.0 with symlinks for frequently used scripts
