fix: default server settings prevent env var config (#1234)

Change configuration source priorities to:

- cli
- environment vars
- dotenv settings
- config file settings
- init settings

By this the environment vars supersede any configuration var
provided by the configuration file or by the initialisation
with pydantic.

The test_config.py::test_computed_path was fixed to to not
use the defaul env var overwrite defined by conftest.py.
This seemed to indicate non working env vars, but in fact
was a test setupt fault.

Besides this fix there are other fixes and changes added:

* fix: exclude computed fields when merging settings

  Pydantic may overwrite settings by values given for computed
  fields and use these values instead of re-computing the field.
  Avoid computed fields in merging settings.

* chore: improve Windows compatability of development setup

  Improve scripts to better run also on Windows. When doing path
  checks keep compatibility also to Windows pathes. A lot of
  changes to avoid the famous Windows CRLF handling and keep
  line endings to LF.

* chore: add development hint for Windows

  Windows developers should set core.autocrlf to false.

* chore: update version

 **Description**: This project provides a comprehensive solution for simulating and optimizing an energy system based on renewable energy sources. With a focus on photovoltaic (PV) systems, battery storage (batteries), load management (consumer requirements), heat pumps, electric vehicles, and consideration of electricity price data, this system enables forecasting and optimization of energy flow and costs over a specified period.
