test(#7510): clean up ruff F401/F841 in the raw-pending-approval test (#7552)

Follow-up to #7551: the merged test file carried an unused `route_approvals as ra`
import and two unused `entry =` assignments (advisory lint gate was red, though not
a required check). Drop them; the two `entry` bindings that are asserted on are kept.
