style(db): biome-format the regenerated migration metadata

drizzle-kit emits _journal.json and the snapshot with expanded arrays, which
biome check rejects. The merge commit used --no-verify, so lint-staged never
formatted them and CI's lint step failed on exactly these two files.

Whitespace only — both files are byte-identical under `jq -S -c`.
