Min RK b5a6b3f590 Avoid downgrading user-env conda/mamba ...

- Only check lower bound on conda/mamba, upgrade unbounded if not matched (let conda apply upper bound according to existing pins, such as Python)
- handle missing mamba
- avoid upgrading Python by aborting the install, instead of keeping old envs
- minimum supported Python for user env is 3.9
- Fix output reporting of conda install step (no need for json capture when we don't parse the output - exit codes will do)
