fix: strip trailing whitespace failing CI format

Two blank lines carry trailing whitespace, so the "Check code formatting"
step (dotnet format --verify-no-changes) exits 1. The CI/CD Pipeline has
failed on master since these were introduced, and because pull_request
builds check out the simulated merge with the base branch, every open PR
inherits the red check.

Whitespace only; no behaviour change.
