I'll admit there were parts of me that really wanted to find some reason to write 2024 Feb 29 24:00. ;)
But, to me, the text of the decree clearly referred to 2024 Mar 1 0:00 or, as your translation puts it, "on the night of February 29, 2024 to March 1, 2024 (at 00:00 hours)".
Nitpick:
As they are repeating 2024-02-29 23.00-24.00 so 2024-03-01 is delayed an hour in
regions observing UTC+6, should this decree not be going into effect on
2024-02-29 rather than 2024-03-01
Most here would almost definitely have written this decree with effect from 24:00 on 29 February, to avoid confusion that any part of 1 March is entered before the 23:xx hour is repeated a second time. But the writers of this decree chose to say 00:00, even though that's technically on 1 March, possibly figuring that specifying "midnight between two dates" would be clearer to the public than saying "24:00" could be.
Fortunately the two approaches are equivalent as far as tzdb is concerned, so we can choose to follow the text.
