Marvin 3af91ed8c0 Fix: Properly initialize original values when loading notes from storage 
When deserializing a Note from JSON, the constructor was called first which
initialized original tracking with empty values. Then the JSON fields were
parsed and set, but hasChanges() would always return true because it compared
the loaded content against empty originals.

Solution: Call markAsSaved() after parsing in fromJson() to update the original
tracking with the actual loaded data.
