Adding search for language selection dropdown (FE)

[MariusJulius]

Language selection dropdowns should have search for better convenience.

To-do:

• add search for vendor price list modal for language selection (same logic as in order creation)
• also check other language select dropwdowns to add seach if not there.

All language dropdowns checked (order creation, tm, vendor price list) - OK
