kaffa 4c4ec24848 refactor: Improve stability and add IPv6 support ...

1. Fix order: Save to disk FIRST, then update HAProxy
   - Prevents inconsistency if HAProxy update succeeds but disk write fails
   - Data is preserved correctly on restart

2. Add IPv6 support
   - Use Python ipaddress module instead of regex
   - Now accepts both IPv4 and IPv6 addresses

3. Extract atomic_write_file() helper
   - Eliminates duplicated code in save_map_file, save_servers_config, haproxy_save_state
   - Single source of truth for atomic file operations
