chore: fix pre-existing dotnet-format whitespace drift

Purely mechanical (object-initializer line-splitting per the project's format
rules) — no behavior change. This drift on develop was blocking the pre-commit
hook's solution-wide 'dotnet format --verify-no-changes' check for unrelated
commits. Verified: diff is cosmetic only (spot-checked), build + all 39 tests
still pass.
