✨🐛Dask-gateway: disable adaptive cluster

[sanderegg]

What do these changes do?

Since cluster adaptive scaling seems to generate a lot of issues when running thousands of jobs this is now disabled.
Therefore the cluster is scaled to a hard-coded huge number (10'000 workers), which should be enough for the time being.

Bonus: some mypy fixes
