feat: Complete CouchDB test infrastructure migration for route tests

- Fixed 5/7 route test suites (auth, events, reports, rewards, streets)
- Updated Jest configuration with global CouchDB mocks
- Created comprehensive test helper utilities with proper ID generation
- Fixed pagination response format expectations (.data property)
- Added proper model method mocks (populate, save, toJSON, etc.)
- Resolved ID validation issues for different entity types
- Implemented proper CouchDB service method mocking
- Updated test helpers to generate valid IDs matching validator patterns

Remaining work:
- posts.test.js: needs model mocking and response format fixes
- tasks.test.js: needs Task model constructor fixes and mocking
