kapillarheizung: state as of 2025-11-26

Comment from Markus:
This needs some redesign. We should not map each
logo parameter to a SECoP module.
I guess that the switch to turn off the heater should be
integrated into the heater modules.

In addition we have to rebase to the wip branch, which would need
a merged version of frappy_psi/logo.py.
