fix: optimize Docker image management during deployment

Enhance the deployment scripts for Finland and Iran by refining Docker image pruning and transfer processes. Implement conditional transfer compression using zstd or gzip based on availability, and ensure only unused admin tags are removed without affecting build cache. This improves efficiency and reduces unnecessary image deletions during deployments.
