Update AutoBlockIPList.py

[itashia]

Major Improvements and Refactoring

Modern OOP Structure

• Codebase has been modularized into clear, single-responsibility classes (DatabaseManager, IPFetcher, IPProcessor, etc.)
• Used @dataclass for better data modeling
• Type hints added throughout for improved readability and maintainability

Error Handling & Logging

• Integrated Python’s logging module for structured logs
• More precise error handling with clear messages
• Improved input validation and safety checks

Performance Enhancements

• Downloading of IP lists now runs in parallel via ThreadPoolExecutor
• Automatically filters out empty entries in IP lists
• Duplicates are removed using set for cleaner output

New Features

• Support for setting max worker threads for parallel fetching
• Enhanced backup logic for reliability
• All classes and methods are now fully documented
• Clearer status messages throughout the process

Code Quality Improvements

• Switched to pathlib for cleaner and cross-platform path handling
• Business logic separated cleanly from execution flow
• Codebase is now more modular and easier to test
• Comprehensive docstrings and inline documentation

Compatibility

• Fully preserves original business logic and database format (Synology-style)
• CLI arguments and functionality remain unchanged

These changes make the code:

• Easier to maintain and extend
• More performant and reliable
• Safer with better error visibility
• Cleaner and more modern — without changing the core functionality
