Accessibility / color issues

[g123k]

Hi everyone,

I test the app on an Eink (= grayscale) phone and a few screens should be improved.

• Bottom bar: impossible to determine which tab is the current (fix: add at least some bold)
  

• Product matching: both colors don't fit well
  

• Search: it's really difficult to understand that we have a bar on top of the screen
  

• Dialogs with sub actions: impossible to understand they are clickable
  

• That one is not related to the UI, but the country picker is particularly long to load.
  We should display a loader when the list of countries is loading

Part of

• 🎯 What can I work on ? #525
