Subject: [PATCH] Docker improvements and decode loading state
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Fix .dockerignore to exclude *.img.xz files (was 2.3GB context)
- Remove deprecated 'version' attribute from docker-compose.yml
- Increase container memory limits to 2GB/1GB (prevent OOM on DCT)
- Add loading spinner to decode button during form submission
