Fix red develop f81b0fdbcfe6

The merge lane found `develop` red at `f81b0fdbcfe6ff22a722082ec641dd8460b14d6e` on its own: no queued PR merges until it is fixed. Failing (tests and gate stages): - `direct-console-issuance-selftest` The whole gate log: artifact `5775` on lane task 7344. Make `develop` pass its full gate again. Open a PR as usual: the merge lane merges a PR that fixes some of these and adds no failure even while `develop` is red.

Fixed the Direct-console issuance selftest: annotation-only sqlalchemy/pydantic imports in operator_settings and url_validation moved under TYPE_CHECKING. Stage went from 101 failed to 161 passed; quick gate green. PR #5969 is queued to the merge lane.
