Add meno axiom to energy transformation and subclasses #2053

[stap-m]

Summary of the discussion

We decided to not use has energy participant and subclasses anymore, see #2053. Also we integrated from MENO energy transformation and energy transfer to replace OEOs own concepts.

Type of change (CHANGELOG.md)

Update

• energy transformation (OEO): added the simplified meno axiom from Make has energy participant obsolete #2053 as subclassOf and remove has energy participant axioms
• added specified axioms to these subprocesses and remove has energy participant axioms:
  • combined heat and power generation process
  • combined cycle electricity generation process
  • electricity generation/gain process
  • fuel-powered electricity generation process
  • combustion thermal energy trafo
  • gas turbine process
  • heat generation/gain process
  • hydro energy trafo
  • hydroelectric energy trafo and subclasses
  • nuclear energy trafo
  • power-to-fuel
  • power-to-gas
  • power-to-liquid
  • power-to-ammonia
  • power-to-methane
  • solar energy transformation and subclasses
  • solar steam electric process
  • water electrolysis process
  • wind energy trafo
  • steam reforming
  • oeo:energy transfer
  • propulsion

[enioarz]

TODOS from the oeo-dev meeting in oldenburg (27.19.25), these axioms should be adapted from EquivalentClass to Subclass:

• electricity generation process:
  • rename to "electricity gain process"
  • alternative label: electricity generation process
  • add comment on why electricity transfer is inferred (matter of perspective)
  • keep equivalence axiom
• same approach for heat generation process
• solar energy transformation

[b-gehrke]

Did we already decide on whether to keep the OEO energy transfer and energy transformation (sub)classes or to replace them entirely? At the moment, both, MENO and OEO classes with the same label, exist.

This PR should wait for #2136 to be merged and then add an update on propulsion.

This PR is waiting for a review for quite some time. Tomorrow is the release and I really would like to include it.
The fist commits were reviewed and agreed upon in a meeting on oct 28 with @b-gehrke @amanda-wein @areleu and me. But the newer commits have not yet received a review. 🙏

Looks good to me, thanks 👍
