refactor: replace lambda with operator.itemgetter in query result sorting

[ogenstad]

Why

These two ruff rules (FURB118, FURB140) were previously suppressed. The fixes are straightforward — operator.itemgetter and itertools.starmap are the idiomatic stdlib alternatives when a lambda or comprehension does nothing but unpack and forward arguments to a function. Enabling the rules and fixing the violations reduces the ignore list and keeps the codebase consistent with the rest of the ruff configuration.

What changed

Removed FURB118 and FURB140 from the ruff ignore list in pyproject.toml and fixed all violations.
