build: migrate Dockerfile + plugin_python from pip/poetry to uv

Dockerfile: drop apt python3/python3-pip, copy the uv static binary from
ghcr.io/astral-sh/uv:latest, install python-build-standalone via
`uv python install` (replacing the manual curl), run aqtinstall via
`uv tool run`, install build-time packages via
`uv pip install --system --break-system-packages --python ...`. Same swap
applied to the CI workflow's inline package-install step.

plugin_python: convert pyproject.toml from [tool.poetry] to PEP 621
[project] + [dependency-groups], drop poetry.lock, replace
abatilo/actions-poetry + `poetry install/run` with astral-sh/setup-uv +
`uv sync/run` in libs/plugin_python/.github/workflows/linting.yml.
