Subject: [PATCH] src/TextUI.cc: fix format arguments

-Wformat detects type mismatch as:

    TextUI.cc:315:34: error: format '%d' expects argument of type 'int',
        but argument 2 has type 'time_t' {aka 'long int'} [-Werror=format=]
      315 |                         printw("%ds",ic->getIdleSeconds());
          |                                 ~^   ~~~~~~~~~~~~~~~~~~~~
          |                                  |                     |
          |                                  int                   time_t {aka long int}
