test: migrate `show_settings` and `version` tests to use `CliTest`
Move `show_settings.rs` and `version.rs` from standalone test files into
the `cli/` module to use the shared `CliTest` test fixture, reducing
boilerplate for tempdir management, snapshot filtering, and command
creation.
Part of #19016.
