Refactor CloudFlare workers

[fivenp]

Why should it be implemented?
Our current worker implementation is extremely immature... We're basically commit the workers to the monorepo but deploy them manually to cloudflare

Describe the solution

• Ideally we'd use lerna or something similar to manage each worker as an own package
• Each worker would be written in typescript
• Workers should be able to share code between each other
• Building and deployment should happen automatically via a GH action or similar

Additional context
There's a nice boilerplate over here:
