#2 No need to merge, submission for code challenge 👾

[nimble-123]

What i've done so far:

• switched to yarn as package/dependency manager
• added missing Typescript types via awesome DefinitelyTyped (@types) project
• enhanced yarn scripts
• added Prettier for code formatting
• fixed typo in border.png filename
• moved UI translation texts to app i18n files
• fixed UI namespace
• ported UI from JavaScript to Typescript
• removed unnecessary console.log() occurrences
• switched to SAP Horizon theme

What's missing from my pov:

• port Express API to Typescript as well
• create MTA descriptor for easy deployment to BTP CF
• create Docker container and K8s scripts for easy deployment to BTP Kyma
• deep dive to watch out for more hints placed by Thomas 😉
