Refactor CloudFlare IP updater to eliminate temporary files

[gpas45]

Summary

Refactored the CloudFlare IP address list updater script to eliminate temporary file operations and improve reliability. The script now downloads the IP list directly into memory and validates entries before updating the address list, preventing the list from becoming empty during updates.

Key Changes

• Removed temporary file handling: Replaced file-based download with direct memory storage using /tool fetch with output=user as-value parameter
• Eliminated file system operations: Removed file creation, deletion, and timeout waiting logic (~40 lines of code)
• Improved update atomicity: Validates all downloaded entries before modifying the address list, preventing empty state during updates
• Enhanced error handling: Simplified error detection by checking response status and content size directly
• Better IPv6 filtering: Explicitly skips IPv6 entries (containing colons) during parsing
• Cleaner code structure: Reduced script from 129 to 97 lines while improving readability
• Updated documentation:
  • Changed minimum RouterOS version requirement from 6.x to 6.43+
  • Fixed scheduler configuration example to use proper syntax
  • Clarified that script downloads current IPv4 networks (not just addresses)

Implementation Details

• Downloads response directly into $content variable, bypassing file system
• Pre-validates all entries into $newList array before updating address-list
• Maintains backward compatibility with existing address-list structure
• Preserves logging for debugging and monitoring purposes
• Removed unnecessary delays and file existence checks
