Does one who prays Fajr in congregation, but does not pray Isha in congregation, have the reward of having spent the entire night in prayer, based on the hadith: "Whoever prays Isha in congregation is as if he spent half the night in prayer, and whoever prays Fajr in congregation is as if he spent the entire night in prayer"?

The wording of the hadith is: "Whoever prays Isha in congregation, it is as if he has spent half the night in prayer. And whoever prays Fajr in congregation, it is as if he has spent the entire night in prayer." What the commentators of the hadith have concluded is that whoever prays Isha and Fajr in congregation is like one who has spent the entire night in prayer, and whoever prays one of them in congregation is like one who has spent half a night in prayer. The meaning of "Whoever prays Fajr in congregation, it is as if he has spent the entire night in prayer" is with the addition of praying Isha in congregation.
