fix(tests): Fix couchdbService mocking issues in model tests

- Fix User.test.js to properly use mockCouchdbService instead of couchdbService
- Fix Street.test.js and Task.test.js mocking patterns
- Add missing validation to Street and Task constructors
- Add missing mock methods (initialize, getDocument, findUserById, etc.)
- Update all references to use mocked service consistently

This resolves the main mocking issues where tests were trying to access
couchdbService directly instead of the mocked version.
