Vlad Doloman b8158e260a Restore Python 3.6 compatibility ...

Remove Python 3.7+ constructs so the tool runs on 3.6:

- Drop `from __future__ import annotations` (3.7+) and convert all
  builtin-generic annotations (list[]/dict[]/tuple[]/set[]) to their
  typing.List/Dict/Tuple/Set equivalents, since without the future
  import these annotations are evaluated eagerly and builtin generic
  subscription only exists on 3.9+.
- Replace subprocess.run(capture_output=, text=) — both 3.7+ — with
  stdout/stderr=PIPE and universal_newlines=True; update the matching
  test assertion.
- requirements.txt: gate cryptography>=41 behind python_version>=3.7 and
  pin cryptography<41 (last 3.6-compatible line, 40.0.2) plus the
  dataclasses backport for 3.6.
- Suppress cryptography 40.x's per-import "Python 3.6 is no longer
  supported" deprecation warning so it doesn't pollute CLI/cron stderr;
  the <41 pin keeps us on a supported release regardless.

The only cryptography API used is AESGCM (present since 2.0), so no
x509/API-surface changes are needed for the older pin.
