Refactor backend to a clean REST API

- Created new 'api' package with testable router and RESTful handlers
- Handlers in 'api' use proper HTTP methods and status codes
- Standardized JSON responses and error handling
- Refactored 'web' package to delegate logic to 'api'
- Maintained backward compatibility for legacy frontend routes
- Simplified 'web/web_test.go' and added comprehensive 'api/api_test.go'
- All tests passing with improved modularity
