fix(ci): install build deps in hive-consume dev mode (#2773)

Add the `setup-env` step to the `dev` matrix entry in `hive-consume.yaml`
so that `pkg-config`, `libsecp256k1-dev`, and `build-essential` are
available when `uv sync --all-extras` has to compile `coincurve` from
source. `coincurve` 20.0.0 has no `cp313` wheel on PyPI, so it builds
from source whenever the uv cache misses; without these system packages
the build fails with `Could NOT find PkgConfig`.
