Proposed Improvements to Postiz Template

I'd like to propose several improvements to the current Postiz template that enhance security, reliability, and configuration flexibility:

The improved template provides a more production-ready setup while maintaining compatibility with Coolify's requirements. It follows best practices for Docker deployments and provides better security out of the box.

Changes

Security Enhancements

• Added Redis ACL configuration with proper authentication
• Implemented secure health checks with authentication
• Enhanced PostgreSQL security configurations

Reliability Improvements

• Added memory limits and resource management for Redis
• Implemented proper data persistence configurations
• Added tmpfs for temporary files
• More comprehensive health check configurations with proper retry/timeout strategies
• Better dependency management with health conditions

Configuration Flexibility

• Support for all environment variables from Postiz documentation
• Added Cloudflare R2 integration support
• Logical grouping of environment variables
• Default values for critical settings
• Better volume management with explicit drivers
