Implement OAuth endpoint logic and enhance test setup

Browse source 
- Added core functionality for OAuth authorization, token handling, and user info retrieval, including error handling and response generation.
- Introduced helper functions for managing different grant types, improving code organization and clarity.
- Enhanced the test setup with a new Prepare function to initialize the OpenAPI test environment and a Clean function for proper resource management.
- Updated tests to ensure the OpenAPI server is correctly loaded and operational during testing.

// Prepare initializes the OpenAPI test environment and starts a mock HTTP server.
//
// AI ASSISTANT INSTRUCTIONS:
// All tests in the openapi package MUST use these utility functions for proper test environment setup.
// This is a preparation utility function, NOT an actual test case.
//
// Usage pattern for ALL openapi tests:
//
// func TestYourFunction(t *testing.T) {
// serverURL := Prepare(t)
// defer Clean()
//
// // Get base URL from server config for correct path construction
// baseURL := ""
// if Server != nil && Server.Config != nil {
// baseURL = Server.Config.BaseURL
// }
//
// // Your actual test code here...
// // Use serverURL + baseURL + endpoint to make HTTP requests
// // Example: http.Get(serverURL + baseURL + "/helloworld/hello")
// // The OpenAPI server will be available as the global Server variable
// }
//
// PREREQUISITES:
// Before running any tests in this package, you MUST execute the following command in your terminal:
//
// source $YAO_SOURCE_ROOT/env.local.sh
//
// This loads the required environment variables for the test environment.
//
// WHAT THIS FUNCTION DOES:
// Step 1: Calls test.Prepare(t, config.Conf) to initialize the base Yao test environment
//
// This sets up database connections, configurations, and other core dependencies
//
// Step 2: Calls Load(config.Conf) to initialize the OpenAPI server instance
//
// This creates the global Server variable that contains the Gin router and all endpoints
//
// Step 3: Creates a Gin router and attaches the OpenAPI server to it
//
// The server uses Server.Config.BaseURL as the base path for all endpoints
//
// Step 4: Starts an HTTP server on a random available port (127.0.0.1:xxxxx)
//
// This allows actual HTTP testing of the OpenAPI endpoints
//
// RETURN VALUE:
// Returns the server URL in format "http://127.0.0.1:xxxxx" where xxxxx is the random port
// NOTE: You need to append Server.Config.BaseURL to construct the full endpoint URL
//
// ERROR HANDLING:
// If any step fails, the test will fail immediately with a descriptive error message.

// Return server URL

// Clean cleans up the OpenAPI test environment and shuts down the test server.
//
// AI ASSISTANT INSTRUCTIONS:
// This function MUST be called with defer in every test that uses Prepare().
// This is a cleanup utility function, NOT an actual test case.
// Always use: defer Clean()
//
// WHAT THIS FUNCTION DOES:
// Step 1: Gracefully shutdown the HTTP test server if it exists
//
// This ensures all pending requests are completed and resources are freed
//
// Step 2: Reset the global Server variable to nil
//
// This ensures no state leakage between tests and prevents memory leaks
//
// Step 3: Calls test.Clean() to clean up the base test environment
//
// This closes database connections, cleans up temporary files, and resets global state
//
// IMPORTANT NOTES:
// - This function should ALWAYS be called with defer to ensure cleanup happens even if tests panic
// - Proper cleanup prevents test interference and resource leaks
// - The order of cleanup steps is important: HTTP server first, then OpenAPI cleanup, then base cleanup
// - Server shutdown has a 5-second timeout to prevent hanging tests
