Fix mypy 1.20.0 compatibility (#20756)

* Fix mypy 1.20.0 compatibility

mypy 1.20.0 introduces improved type narrowing and stricter enum/dict
inference that breaks the existing codebase. This fixes all 20 errors:

- Remove `types-cryptography` (3.3.23.2): ancient stubs conflict with
  cryptography 46.0.6's own `py.typed` inline types. mypy 1.20.0 now
  resolves enum member annotations from stubs as `str` instead of the
  enum type, causing arg-type errors in SSL code.
- Remove stale `type: ignore` comments made unnecessary by improved
  narrowing (equality checks on unions, dict key membership).
- Add targeted `type: ignore` for new stricter dict union inference
  (bool/int distinction in literals, conditional dict merges).
- Fix pre-existing RUF070 lint errors in touched files.

* Bump mypy to 1.20.0 in poetry.lock

The previous poetry.lock pinned mypy at 1.19.1, so CI was running
the old version despite the code fixes targeting 1.20.0. This updates
the lock file to resolve mypy 1.20.0 (and its runtime dep librt 0.8.1).
