Enhance logging system with detailed product tracking and console cleanup

- Added comprehensive product logging to match order detail level
- Moved all debug console messages to proper log files
- Added JSON structure analysis logging for both products and orders
- Enhanced per-page progress tracking with counts and warnings
- Unified logging format with [PRODUCTS] and [ORDERS] prefixes
- Removed SET STEP ON debug statement
- All debug information now properly logged instead of console output

 ## Project Overview
 
-This is a Visual FoxPro 9 project that interfaces with the GoMag e-commerce API. The main component is a script for retrieving product data from GoMag's REST API endpoints.
+This is a Visual FoxPro 9 project that interfaces with the GoMag e-commerce API. The application retrieves both product and order data from GoMag's REST API endpoints with full pagination support and comprehensive error handling.
 
 ## Architecture
 
-- **Single File Application**: `gomag-vending.prg` - Main Visual FoxPro script
+- **Main Application**: `gomag-vending.prg` - Primary Visual FoxPro script with pagination support
+- **Utility Module**: `utils.prg` - INI file handling, logging, and helper functions
+- **JSON Library**: `nfjson/` - Third-party JSON parsing library for VFP
 - **Technology**: Visual FoxPro 9 with WinHttp.WinHttpRequest.5.1 for HTTP requests
-- **API Integration**: GoMag REST API v1 for product management
+- **API Integration**: GoMag REST API v1 for products and orders management
 
 ## Core Components
 
 ### gomag-vending.prg
-Main script that handles:
-- GoMag API authentication using Apikey and ApiShop headers  
-- HTTP GET requests to retrieve product data
-- JSON response parsing and analysis
-- File output for API responses (timestamped .json files)
-- Error handling and connectivity testing
+Main application script with:
+- Complete pagination support for products and orders
+- Configurable API settings via INI file
+- Comprehensive error handling and logging
+- Rate limiting compliance (1-second delays between requests)
+- JSON array output generation for both products and orders
 
-### Key Configuration Variables
-- `lcApiUrl`: GoMag API endpoint (defaults to product read endpoint)
-- `lcApiKey`: GoMag API key (must be configured)
-- `lcApiShop`: Shop URL (must be configured)
+### utils.prg
+Utility functions module containing:
+- INI file operations (`ReadPini`, `WritePini`, `LoadSettings`)
+- Logging system (`InitLog`, `LogMessage`, `CloseLog`)
+- Connectivity testing (`TestConnectivity`)
+- URL encoding utilities (`UrlEncode`)
+- Default configuration creation (`CreateDefaultIni`)
+
+### settings.ini
+Configuration file with sections:
+- `[API]` - API endpoints, credentials, and headers
+- `[PAGINATION]` - Page size limits
+- `[OPTIONS]` - Feature toggles for products/orders retrieval
+- `[FILTERS]` - Date range filters for orders

 ### Running from Windows Command Line
-Use the provided batch file for easy execution:
+Use the provided batch file:
 ```cmd
 run-gomag.bat
 ```
 
-Or directly with Visual FoxPro executable:
+Direct execution with Visual FoxPro:
 ```cmd
-"C:\Program Files (x86)\Microsoft Visual FoxPro 9\vfp9.exe" -T "path\to\gomag-vending-test.prg"
+"C:\Program Files (x86)\Microsoft Visual FoxPro 9\vfp9.exe" -T "gomag-vending.prg"
 ```
 
-The batch file uses `%~dp0` to automatically detect the current directory, making it portable across different locations.
+## Configuration Management
 
-### Testing Connectivity
-The script includes a `TestConnectivity()` function for internet connectivity testing.
+The application uses `settings.ini` for all configuration. Key settings:
+
+### Required Configuration
+- `ApiKey` - Your GoMag API key
+- `ApiShop` - Your shop URL (e.g., "https://yourstore.gomag.ro")
+
+### Feature Control
+- `GetProducts` - Set to "1" to retrieve products, "0" to skip
+- `GetOrders` - Set to "1" to retrieve orders, "0" to skip
+- `OrderDaysBack` - Number of days back to retrieve orders (default: 7)
+
+### Pagination
+- `Limit` - Records per page (default: 100, max recommended for GoMag API)
 
 ## API Integration Details
 
 ### Authentication
-- Uses header-based authentication with `Apikey` and `ApiShop` headers
-- Requires User-Agent to be different from "PostmanRuntime"
+- Header-based authentication using `Apikey` and `ApiShop` headers
+- User-Agent must differ from "PostmanRuntime"
 
-### Endpoints Used
-- Primary: `https://api.gomag.ro/api/v1/product/read/json?enabled=1`
-- Supports pagination, filtering by category/brand, and sorting parameters
+### Endpoints
+- Products: `https://api.gomag.ro/api/v1/product/read/json?enabled=1`
+- Orders: `https://api.gomag.ro/api/v1/order/read/json`
 
 ### Rate Limiting
-- No specific limitations for READ requests
-- POST requests limited to ~1 request per second (Leaky Bucket algorithm)
+- 1-second pause between paginated requests
+- No specific READ request limitations
+- POST requests limited to ~1 request per second (Leaky Bucket)
