Subject: [PATCH] [ADD] pos: implement second UoM

- Add pos_second_uom_id to product template.
- Implement  inherited from NumberPopup to handle
  quantity entry in secondary units.
- Patch ControlButtons to include a second UoM button.
- Add conversion logic to calculate the main UoM quantity based on
  absolute factors.
