Extract some store translation work from StoreEdit

What does this MR do?

• Remove some duplicate translations + Consolidate store breadcrumb translations
• Modernize store bubble translations (extracted from !1469 (closed))
• Add new store status "does no longer exist" for permanently closed stores (they don't show up on the map)
• Minor trafficlight cleanup and de-Germanization

How confident are you it won't break things if deployed?

Should be okay. I didn't test the quiz change exhaustively, yet.

Links to related issues

• !1469 (closed)
• closes #786 (closed)
• closes #818 (closed) (by removing that functionality from the main store screen, still available when editing)

How to test

• configure a store so that various public info shows up on the map bubble
• visit page=map&bid=1234 (whichever ID your store has)
• also check the main store screen, the store-edit screen
• play around with the traffic light stuff (set different values)
• and of course check the traffic light usage in the quiz

• Once your MR has been merged, you are responsible to create a testing issue in Beta Testing Repo:
  • Consider writing a detailed description in German.
  • Describe in a few sentences, what should be tested from a user perspective.
  • Also mention different settings (e.g. different browsers, roles, ...). how this change can be tested.
