feat(260403-qhw): add conda environment.yml and conda-test CI job

- Add environment.yml with Python 3.12 and pip editable install of .[dev,monitoring]
- Add conda-test CI job using conda-incubator/setup-miniconda@v3
- All run steps use shell: bash -el {0} for proper conda environment activation
- Job verifies module imports and runs unit tests under the conda environment
