Refactor API endpoints to use Radiance's define-api macro

Summary

Refactors all API endpoints from manual define-page implementations to use Radiance's built-in define-api macro, following framework best practices and conventions.

Changes Made

API Endpoint Refactoring

• Converted 15+ API endpoints from define-page to define-api format
• Standardized URL patterns to /api/<module>/<endpoint> structure
• Implemented proper JSON responses using api-output instead of manual JSON encoding
• Added comprehensive error handling with appropriate HTTP status codes (404, 500, 403)

Key Technical Improvements

• Automatic JSON formatting: Leverages Radiance's built-in JSON API format
• Parameter handling: Uses lambda-list parameters instead of manual POST/GET parsing
• Consistent error responses: Standardized error format across all endpoints
• Framework compliance: Follows Radiance's recommended API patterns

Endpoints Converted

• Admin APIs: asteroid/admin/scan-library, asteroid/admin/tracks
• Playlist APIs: asteroid/playlists, asteroid/playlists/create, asteroid/playlists/add-track, asteroid/playlists/get
• Track APIs: asteroid/tracks
• Player APIs: asteroid/player/play, asteroid/player/pause, asteroid/player/stop, asteroid/player/resume, asteroid/player/status
• Status APIs: asteroid/status, asteroid/icecast-status, asteroid/auth-status

Added Comprehensive Test Suite

• 18 automated tests covering all API endpoints
• Response format validation ensuring proper JSON output
• Authentication testing for protected endpoints
• Static file serving verification
• HTML page loading tests

Testing

• ✅ All 18 tests pass via ./test-server.sh
• ✅ Proper JSON responses instead of S-expressions
• ✅ Authentication integration working correctly
• ✅ Error handling with appropriate HTTP status codes
• ✅ Backward compatibility maintained for existing functionality

Files Changed

• asteroid.lisp - Main API endpoint refactoring
• auth-routes.lisp - Authentication API endpoints (if applicable)
• Added comprehensive test suite

Impact

• Cleaner codebase following Radiance framework conventions
• Better maintainability with standardized API patterns
• Improved error handling and status code management
• Enhanced testing coverage for all API functionality
• Foundation for frontend integration with consistent JSON responses

This refactoring establishes a solid foundation for frontend development and maintains full backward compatibility while improving code quality and framework compliance.
