bugfix [#25290] Align on text gives a traceback

       [#25284] Traceback error on "System Info" script

- Align was only working on mesh objects, now operate on all objects, missing boundbox's are treated as single points.
- obj.bound_box was returning all nan's for object types with no boundbox.
- ENUM_FLAG type enums were showing no text when displayed in operator redo panel.
