[FEAT] Show github sha on frontend

[sellnat77]

Overview

For the purpose of identifying builds, we should put a frontend component that shows what github hash is currently being served from the frontend and from the backend

More often than not, the frontend version will match the backend but i think it is possible for the two versions to drift apart so we want to be able to retrieve both versions from the ui

Action Items

• UI Design
  • To be linked after complete
• Frontend retrieve github sha from ???
• Frontend to retrieve backend github sha from GET https://${DB_URL}/healthcheck
  • See [Service] Healthcheck service #359 for response format
