Subject: [PATCH] Handle SIGTERM and SIGINT for clean exit

Adds handlers for SIGTERM and SIGINT signals using the existing sa_usr2()
handler, which cleanly exits with YAD_RESPONSE_CANCEL.

This allows scripts to properly terminate YAD dialogs when interrupted
(Ctrl+C) or when receiving SIGTERM from process managers.

Follows feedback from PR #314 about reusing existing handlers instead of
creating new ones.
