Now that flow has better support for flow, we need to update our mobile-native configuration to do static analysis at the CI level and catch any type errors / null

• Upgrade our flow typing and make sure we've got our stack up to date.
• Make the app compile with flow (wernt went massive breaking refactor, less bad because we already have flow started)
• Add static analysis checking to the CI flow
• Make sure the app builds and deploys
• End to end tests pass (this part shouldn't break too much)
• unit tests pass (this part will probably break hard)

changed milestone to %Sprint::02/26 Calculated Cricket

added scoped labels

changed weight to 24

changed title from static analysis for react native to static analysis for react native

changed weight to 25

Keeping this at 24, because we're going to need to define all the types in flow which will cause lots of breakage.
