Prioritize human-readable names in CLI output (#25869)
Summary
--
This PR swaps the rule name and code in our `--show-fixes` output, which
previously looked like
this:
<img width="324" height="107" alt="image"
src="https://github.com/user-attachments/assets/32dff652-421c-4e7a-adbd-ac87cc740965"
/>
and now looks like this in preview:
<img width="314" height="103" alt="image"
src="https://github.com/user-attachments/assets/d7d942d6-d5a5-4622-b9a2-a271eb5b0663"
/>
The actual code change is just for this one flag, but I also examined
the other CLI flags (besides
diagnostic output formats, which I'll update separately) and think that
nothing else needs to be
updated. The other two main candidates were `--statistics` and
`--show-settings`, but these already
show both codes and names prominently. `--show-settings` even
prioritizes them over codes:
```console
❯ ruff check --no-cache --ignore-noqa --statistics
1 F401 [*] unused-import
Found 1 error.
[*] 1 fixable with the `--fix` option.
❯ ruff check --no-cache --show-settings
...
linter.rules.enabled = [
multiple-imports-on-one-line (E401),
module-import-not-at-top-of-file (E402),
...
]
...
```
