According to https://www.planespotters.net/airframe/airbus-a320-200-ra-73..., the plane was leased from AerCap and registered as VQ-BFW (Bermuda) until 23 Mar 2022, and then re-registered as RA-73807 - so yes, this is one of the stolen planes. But the spare parts situation is not related to that...
I have found an article https://www.reuters.com/business/aerospace-defense/aircraft-... about AerCap receiving 645 million dollars for 17 (or 18?) aircraft used by Aeroflot, but Ural Airlines being independent of Aeroflot, I don't think this plane is part of that agreement.
