/**
 * Press Button - An interactive button that requires holding for a configurable duration before triggering its action.
 *
 * @description
 * The Press Button is a safety-focused button designed for destructive or high-impact actions
 * such as deleting resources. Unlike a standard button, it requires the user to press and hold
 * for a configurable countdown duration before the action fires. While held, a progress bar fills
 * the button background from left to right, providing visual feedback. If the user releases before
 * the countdown completes, the action is cancelled and the progress resets. This prevents accidental
 * triggering of critical operations.
