refactor: make modbus controller cross-platform and improve locking

Browse Source 
- Added cross-platform file locking using msvcrt (Windows) and fcntl (Unix).
- Switched to pathlib for robust path management and automatic directory creation.
- Updated is_host_reachable to support Windows ping syntax.
- Added atexit handler to ensure lock file descriptors are closed properly.

NOTE: Verified on Linux (LMDE 7). Windows compatibility implemented but not yet tested.
