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
