Add language picker to locations page and add warning that search is only in English, make quick exit button the same across all pages

• If I picked the wrong language or I have a VPN and I open the locations page right away, I can't change the language. • The quick exit button has 3 different styles on the home, location, and pin pages, it is inconsistent and can affect the cyber safety of the individual • We need to warn users using different languages to search English terms only
