The manufacturing shop floor interface has been refined to make common actions clearer and reduce confusion for operators. Dialog sizing, button labels, visual cues, and menu options were adjusted so users see more accurate actions at the right time.

In this commit:
=====================
- resized the Add Component modal to medium size.
- renamed 'Open Backend MO' to 'Open Manufacturing Order' in the MRP menu dialog.
- updated the behavior of the 'Register Production' button to only be crossed out 
  upon clicking the validate button in the register production dialog.
- styled the 'Register Production' button as a link.
- made 'Print Barcode Commands' invisible when the work order is not activated.
- replaced fa-plus icon with gear icon in shop floor module.
