2026 Version

This is the version as it was run for our students for the Spring Semester 2026, with some additional bug fixes afterward.
This version matches the 26 Tag of the Docker containers on Dockerhub.

Some of the updates:

• Complete rewrite of the setup and cleanup to use Python in the background instead of bash, to make it more readable and maintainable
• The script to restart containers is also rewritten in Python, but the old shell script version is kept for now, just in case. (We have tested the new script a bit, but not super extensively)
• We have integrated a new tab into the webpage that allows students to visualize traceroutes on the topology. (provided by @FuhrmannMartin)
• Introduced Tags for our Docker containers to help us with development and to keep older versions of the mini-internet available if needed.
• Cleanup of old and unused files
• The history container shouldn't create any zombie processes anymore.
• Moved the measurement container port from 2099 to 2999 to avoid overlap in case there is a group 99.
