Step to reproduce:

- Change the language to any language other than english
- Go to PoS and open a session
- Click on "Client" and select a client
- The button 'Select Customer', 'Deselect Customer' and 'Change Customer'
  are not translated.

Cause of the issue

- The term 'Change Customer' was missing in pos.pot
- Translation was not enabled in JS file
