Fix issue setting the lookback default after it gets used

[taldcroft]

Description

PR #351 introduced a problem in kadi commands update processing where the lookback value (None by default) was being used in a computation prior to being set to the conf.default_lookback value. This was temporarily fixed in production by adding the --lookback=30 flag to the script command.

This PR does two things:

• Move the lookback update to the top of the function before it gets used.
• Change the test of the command archive update process to not supply the --lookback argument. This matches the way the script is called in production.

This PR also includes an unrelated fix for ruff 11.0. There are no code changes so I did not re-run unit tests.

With only the 1st commit, the test_commands_create_archive_regress test fails with the same exception seen in production processing.
