Subject: [PATCH] fix: Resolve Docker permission issues in development
 environment
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Create dedicated Dockerfile.backend.dev for development with proper permissions
- Set user UID/GID to 1000 (common for development systems)
- Create logs and temp directories in Dockerfile before switching user
- Use named volumes for logs, temp, and node_modules to maintain permissions
- Mount only source files instead of entire backend directory
- Remove complex entrypoint script in favor of simple CMD
- Add LOG_DIR and TEMP_DIR environment variables

This fixes the "Permission denied" errors when creating directories in Docker.
