fix: resolve CouchDB test infrastructure issues

- Fix Badge.js model to use correct couchdbService.createDocument() method
- Update Badge.test.js with proper static method testing patterns
- Add missing Post model import in Post.test.js
- Update jest.setup.js with missing mock methods (get, destroy)
- Fix PointTransaction.test.js mock service definition
- Ensure consistent mock patterns across model tests

User and Badge model tests now pass with 40/40 tests working.
Post test import fixed, remaining test issues identified for next iteration.
