20240827update

The life expectancy death determination for ronin had been omitted, which sometimes resulted in the appearance of very old generals,
　Therefore, a simplified life expectancy death judgment is now periodically performed for ronin as well.
Added some wording to the tutorial.
The owner of hidden abilities can now be selected as random or fixed by default.
(Previously, when randomizing human nature, the owner was randomized together with it.)
Added the ability [Fenix2] (an ability for ability synthesis only).
Fixed some omissions in translation.
Other minor fixes
