Improve colors

General feedback from all our users:

What should make more sense with the buttons/UI colors based on what is generally used

Blue: Translated
Green: Approved
Red: Rejected
Orange: Needs work

With those colors:
Blue will give a unity to the whole UI in each string button
Green is the general approved color in people minds
Rejected needs to be seen > red is perfect
Orange for the needs work helps to see it as well. The actual Yellow on white doesn’t work as expected
