Review Comment:
   A persisted saved query can have a null `db_id`, but these new datasource 
properties immediately dereference `self.database`. Creating or updating a 
chart against that row still fails with `AttributeError` during 
access/persistence instead of returning a controlled validation or 
authorization error. Could this path reject database-less saved queries or 
handle the absent database safely?
