style: apply prettier to route tool schemas and smoke test

CI runs format:check on every PR; this is the first PR to trigger it
since the workflow was added. The avoid_tolls one-liner in three route
tools (introduced in #80) and a long console.log line in the new transit
test both exceeded prettier's print-width and are split to match the
existing avoid_highways formatting. No semantic changes.
