pos*: point_of_sale, pos_hr, pos_restaurant
In this PR we fix a number of small UI issues in the point of sale app.
Issues fixed:
- Align filter option in the TicketScreen search bar;
- Align items in the opening popup that shows the available
login options in the pos_hr module;
- Align tips column in ticket screen;
- Made it so clicking on the employee icon does not open the
selection popup if there is only one employee configured
( as it will be empty in this case );
