chore: Enable ty unused-ignore-comment rule

[vdusek]

Summary

Now that ty supports detecting unused suppression comments (upstream issues astral-sh/ty#278 and astral-sh/ty#1501 are closed), enable the unused-ignore-comment rule project-wide so obsolete # ty: ignore[...] comments are caught automatically.

Verified that all current # ty: ignore[...] suppressions in the codebase are still required (none had to be removed).

Closes #1664.
