fix(models/user-badge): normalize find results and return updated docs; remove duplicate methods

Unifies handling of couchdbService.find array/{docs} shapes, ensures create/update return full docs with _rev, and deduplicates overlapping methods (findByUser, findByBadge, findByUserAndBadge, update). Adds robust update fallback to support both updateDocument(doc) and update(id, doc). Resolves test failures around inconsistent shapes.
