How do we reconcile the Hadith "No disobedient person shall enter Paradise" with the existence of sins that a believer habitually commits or persists in?

Monotheists who have committed sins will certainly enter Paradise. Some of them may enter Hell to be purified from their sins, for Allah the Almighty says: "Then among them are those who wrong themselves, and among them are those who are moderate, and among them are those who are foremost in good deeds by Allah's permission. That is the great bounty. Gardens of perpetual residence; they will enter them."

And whoever dies without associating anything with Allah will enter Paradise, even if they fell short in obligations or committed some forbidden acts. They may be punished in their grave or in Hell, then be released after purification, or Allah may forgive them.

As for the hadith "A disobedient person will not enter Paradise," it is weak. Even if it were authentic, it would be interpreted to mean that they will not enter it as an initial entry.
