Add threat actor location: can't create a location + bad design

[Archidoit]

• Go to the overview of a threat actor group.

• Add a location
  

• The header design of the add location panel is not correct
  

• We can't create a location from this place (the 'add' pink button is missing).

I don't think we want the pink "create button" on the Add Location Panel. It is also not the case in Intrusion Set. What should I do @Jipegien ?

Add the creation button. Threat actor(group), threat actor(individual) and Intrusion set panel.
Fix the position of the search bar.
Add french translation for located at.
