chore: start using the FastAPI version and other cleanup (#256)

* Set the current version in the FastAPI constructor and use
`app.version` elsewhere
* Update version-sync commands accordingly
* Do not dump stack traces for unhandled errors
* Add a startup log, other startup is silent without `uvicorn.error`
