Fix issue #14: Set Up Swagger API Documentation

[cld-vasconcelos]

This pull request fixes #14.

The issue has been successfully resolved based on the concrete changes made:

1. The required drf-spectacular package was properly installed via Poetry and added to dependencies
2. All necessary configuration was added to settings.py:
   • drf-spectacular added to INSTALLED_APPS
   • DEFAULT_SCHEMA_CLASS configured for REST framework
   • Comprehensive SPECTACULAR_SETTINGS added with proper JWT auth support
3. The required API documentation endpoints were added in urls.py:
   • /api/docs/swagger/ for Swagger UI
   • /api/docs/redoc/ for ReDoc
   • /api/schema/ for the OpenAPI schema

The changes directly address all acceptance criteria:

• Swagger and ReDoc endpoints are properly configured at the specified URLs
• Auto-generation of API docs is enabled via the DEFAULT_SCHEMA_CLASS setting
• JWT authentication is configured in SPECTACULAR_SETTINGS with proper Bearer token support

The implementation uses standard Django/DRF patterns and follows the drf-spectacular documentation recommendations. The configuration will automatically generate documentation for any API endpoints added to the system, making it maintainable going forward.
