Change project dependency manager from poetry to pdm/uv

[Ingerid]

Endringer

• Oppdater prosjektversjonen til 2.42.0 i pyproject.toml
• Legg til nye konfigurasjonsblokker i pyproject.toml som er agnostiske mht. uv, poetry eller pdm.
• Fjern alle gamle [tool.poetry]-blokker
• Slå sammen dependency groups dev og test, og fjern mypy, pandas-stubs og numpy fra depedencies. Numpy installeres uansett via pandas.
• Fjern spesifikke versjoner fra dependencies, slik at pakkeversjonene kan løses ulikt for ulike pythonversjoner (gjelder særlig python 3.10-3.11 for flere pakker, og numpy 1.2-2.0 for python 3.13)
• Bruk uv i CI.yml (github actions) istedet for poetry
• Legg til python 3.13 i testregimet slik at dhlab dekker alle offisielt "stabile" python-versjoner
• Oppdater til å bruke uv i release.yml også.
• ignorer lock-filer

pyproject.toml:107

• The Poetry test dependencies section contains duplicated dependencies that are already defined in the new PEP 621 test dependency group (lines 65-69). This creates maintenance overhead and potential version conflicts. Consider removing this Poetry section or ensuring version consistency.

[tool.poetry.group.test.dependencies]
mypy = "^1.6.1"
pytest = "^7.4.3"
pytest-cov = "^4.1.0"
