- Added a wrapper around express.Router to our shared/express util
- Also export static and _express
- Use this shared util everywhre, meaning express is only used directly in this one file
- ATM this file is mostly an experiment / debug helper, it might be removed again later
- The aim is to have a minimal framework wrapping express that allows us to:
- reduce our usage of express() in favour of Router()
- unify some of our duplicated logic
- fix some structural issues e.g. Sentry
- make it easier to understand the codebase
