Brent Westbrook 8199154d54 [ty] Fix a few more diagnostic differences from Ruff (#19806) ...

## Summary

Fixes the remaining range reporting differences between the `ruff_db`
diagnostic rendering and Ruff's existing rendering, as noted in
https://github.com/astral-sh/ruff/pull/19415#issuecomment-3160525595.

This PR is structured as a series of three pairs. The first commit in
each pair adds a test showing the previous behavior, followed by a fix
and the updated snapshot. It's quite a small PR, but that might be
helpful just for the contrast.

You can also look at [this
range](052e656c6c..c3ea51030d)
of commits from #19415 to see the impact on real Ruff diagnostics. I
spun these commits out of that PR.

## Test Plan
