Nut Could Not Load Keys.txt Access

ERROR: keys.txt not found in current directory (/app/). Searched also: ~/.config/nut/keys.txt, /etc/nut/keys.txt.

Bonus Feature: --check-keys flag Runs only the key loading logic and reports success/failure without running main program – useful for scripting and debugging.
