Make packages/medusa/src/services/claim.js pass eslint

Editor assessment

The subject is unambiguous about the mechanical change: packages/medusa/src/services/claim.js was made to pass ESLint. The trouble is the type — fix promises a defect resolved, when lint compliance is a style or chore concern, so the classification misdirects readers filtering for bug fixes. No scope is present, though the file path embedded in the subject does the locating. No body exists to explain why the file was out of compliance or what rules were touched. Understandable as far as it goes, with a type choice that muddies an otherwise clear statement.
