Update Zalmoxis with temperature-dependent EOS feature

[flaviacris03]

Description

This PR integrates the newest version of Zalmoxis 26.01.06 into PROTEUS.

General Workflow: Zalmoxis prescribes the initial temperature profile (initial thermal state of the planet). Based on defined constraints (mass, CMF etc.), Zalmoxis solves the interior structure and determines the location of the core-mantle boundary (CMB). The resulting mantle temperature profile is then rescaled and passed to Aragog using its prescribed initial-condition temperature mode. Aragog subsequently takes over and computes the planet’s long-term thermal evolution.

Closes Issue 37 from Zalmoxis.

Validation of changes

• Ran a grid of simulations for 1-6 EM with all_options.toml with 'zalmoxis' as struct module for default values.

Tests pass on MacOS with Python 3.12.9.

Great, let us know when you want feedback on this.

I ran a grid of simulations for 1-6 EM planets using all_options.toml, with zalmoxis as the [struct] module and default parameter values. Since the [orbit] module uses lovepy as default, the simulations run for several 10s of timesteps before crashing with a LovePy error (matrix contains Infs or NaNs). This seems to occur after RF_depth reaches zero.

Running the identical grid with the dummy [orbit] module completes without issues, and all planets fully solidify.

@timlichtenberg I'm not sure whether this behavior is an issue for this PR or should be handled separately, but it needs to be discussed.

[timlichtenberg]

Let's put the orbit module to dummy for the time being for all_options.
