Turn on mypy warn_return_any (pyproject) and resolve the 84 resulting [no-any-return] errors across 43 files with typing.cast() at the return sites — runtime no-ops that make the declared return type explicit where a dependency (SQLAlchemy scalar/first/one, httpx .json(), subprocess, docker SDK) hands back Any. No behavior change: no DTO/table field types altered, no validation/coercion calls added, every cast reflects the true runtime type. Locks in return-type strictness so the class of bug where a function silently widens to Any can't regress. mypy decnet/ clean; adversarially verified behavior-preserving (84 casts 1:1 with prior returns). Bump tornado 6.5.5 -> 6.5.7 (CVE-2026-49854, transitive via snakeviz).
