TurboSpruce test for 2025

This MR

• Adds test for turbospruce on 2025 config
• Means that authors will be prompted to set the stream attribute of new lines

• Assign a line a stream to check it works
• Improve failure coverage
• Lines to add stream
• Disable for detdesc
• Test failure if a non-existant stream is set as attribute
• Look at print(f"prefix: {prefix}, output: {output}") for full 2025 test to make sure its sensible topo stuff is OK
