feat(mobile): show in app survey

[bonomat]

resolves #1810

Feature in a nutshell:

• the coordinator's db has the polls and their possible choices.
• polls can be disabled or enabled in the db
• answers are also stored in the db
• the user caches on their side if the poll was already answered
• the user can also decide to ignore the poll forever (in case he doesn't want to give an answer).

With this we can also send messages to all users which are shown in app :)

It's great!

questions :

-> Can we run different polls like this on different screens (or just on homescreen)?
-> Can we condition a poll (e.g. whether the user has already taken a certain action in his journey, or not)?

Both questions: not yet, but keep ideas coming and we might add them in the future :)
