fix(api): use js-yaml named imports for v5 compatibility

js-yaml v5 is ESM-only and dropped its default export, exposing only
flat named exports. The profile export route imported the default
(`import yaml from 'js-yaml'`), so `yaml.dump()` threw and the export
endpoint returned 500. Switch to named imports (`dump`/`load`) in the
route and its test.
